Transparency Effect bug - Effects all objects on spread instead of only selected object.

I select a regular rectangle shape object with a solid fill (yellow) and change it's transparency under the effects menu to 75%. I have another regular rectangle object with a solid fill (turquoise) that's transparency is 100%. However, once I change the yellow rectangles transparency to 75%, the turquoise rectangle appears as if I've also changed it's transparency to 75% - not the desired result. When I change the yellow rectangle object back to 100% transparency, the turquoise rectangle object appears at it's original 100% transparency state. The change in transparency also effects the color of other objects on the same layout.

Adobe Indesign 2019 v 14.0.2
Windows 10

Using version 14.0.2 x64 under Windows 10.

Working on a 356-page book. Three types of crashes occur consistently:

1 - When I export to PDF.
2 - When I add pages, usually in increments of 10.
3 - When I switch between single-page layout and 2-page spread layout.

After every crash, when I go to open the file, inDesign offers to auto recover the file. When I say yes, InDesign warns me that the file might be corrupt. I always open anyway. After 3 months working on this book, I can't afford to start over, so I hope for the best.

Three of the crashes have caused significant problems.

1 - The first 38 pages had been deleted. I had to completely redo them.
2 - The even-page master had been applied to all pages. I had to highlight all the odd pages and re-apply the odd-page master.
3 - Tonight's crash resulted in master pages designations and therefore page numbers on all 356 pages being deleted. I have to highlight all the odd pages, re-apply the odd-page master, highlight all the even pages, and re-apply the even-page master.

I have been using InDesign since the PageMaker days but my experience over these past three months is going to cause me to look elsewhere.... Word, Blurb, etc.

Accessibility Checker fails:
Check boxes (Tagged form fields - Failed)
Radio buttons (Tagged annotations - Failed)
InDesign copy changes, Acrobat Reading order missing tags.

Using MacOS High Sierra V 10.13.6.

Previous files, InDesign 2018 Export Adobe PDF Interactive Passed the checker.
Duplicate the pdf and rerun the checker and it passes.

Same file open in newer version InDesign 2019 Export Adobe PDF Interactive fails. This tells me the problem is with Indesign 2019.

This is happening with all my files. If I take a new Indesign file with no interactive functions and create them in InDesign 2019 everything passes.

Indesign file attached with good pdfs and if you export the same Indesign file and run the accessibility checker it will fail in 2019 InDesign.

Copying a number of items from one document to another, all of the text that did not have an outline had its overprint attribute turned on, despite being off in the source file. It was particularly annoying to fix because most of the text was white (Paper swatch), for which the overprint setting is uneditable: I had to turn all the white text to a different colour, uncheck the overprint, then make it white again. (Using InDesign v14.0.2 on Mac OS v10.12.6.)

IMO there should never be a reason to overprint items using the Paper swatch anyway, so this attribute should get turned off rather than just being disabled, which has the effect of ‘locking in’ the current state no matter how inappropriate.

Drawing a box, moving it around etc is now a kind of laggy. Moves but slow and kind of stuttering.

The GUI overall, menus etc, behaves a bit slower as well. Not much but not as quick and responsive at it was in Sierra.

Have tried de-activating GPU but that has no difference at all.

I have the latest version, 14.0.2.
Updated to Mojave because the Adobe chat support suggested that would help out some other issues I have had.
One reason was that command + new shortcut stopped working. And now it stopped working again...

Same thing happens in Illustrator so it seems to be something of a Mojave comparability?

Other software (non-adobe) seems to be just fine though.

Using a Imac 2017, i7, 32 ram, 1 tb ssd.

I'm a big fan of technology but in Adobes case it seems as going back a few years actually was better having a lot fewer issues in the software.
(For me it all started with the bloody CC subscription thing.)

InCopy 14.0. MacOs Mojave 10.14.4
I work in a icml-document which was assigned to me from InDesign. It contains references to other documents and a lot of comments (for the designer).
After I have made the third or later comment, it becomes impossible to select text. InCopy selects the text from the top of the document upto the point where I click the mouse. When I try Option+Shift+Arrow, the cursor jumps to the top of the document. I can save the document, after which the issue is away until I have made a few extra comments, but which also puts the cursor again at the top of the document. This is unworkable, because I continually have to search the position I was editing.
I have tried to switch from Adobe CC to iCloud Drive, this makes no difference.
I have tried to copy all the content to a fresh document, this also makes no difference.
I unfortunately cannot attach the document that I am working on, because this page does nog accept icml-files of a zipfile.
