Version: Indesign CC 13.0 x64 Windows (and Indesign CC 2017)

1. Create 2 paragraphstyles
2. For ParagraphStyle 1 set bullets and numbering To List Type 'Numbers' and name it 'Multiple Choice' (or something else) and Level 1
3. For ParagraphStyle 2 base it on ParagraphStyle 1 and change the text color
4. Create some paragraphs with different combinations of these styles.
5. Save as idml
6. Open the idml
7. Look at the paragraphs of the second paragraphstyle, you will notice that paragraphStyle 2 has a numbering of his own and no longer the mix with paragraphstyle 1.

Expected result: Same as before the save to idml. A list with a. b. c. d. e.
Actual result: list looks wrong like a. a. b. b. c.

It only happens when the second paragraphstyle is based on the first style. But working with styles that are not based on eachother is going back in time.

Attached you will find the correct indd that you can save as idml and see the result.
Also I added 2 screenshots, 1 correct, 1 wrong after idml.

1) This bug occurred on InDesign cc2017 and CS6. 2) Follow these steps to replicate the bug: create a shape, let's say a circle, and then copy this circle and paste it in a separate layer directly over the top of the first. To better see the effects of the bug, make the fill of the top circle red, and the bottom blue. At this point, the bottom blue circle is completely hidden by the red circle above it. Now put a 4pt stroke with an outside alignment on the bottom blue circle. The blue circle is still hidden, and now it appears as if the red circle on top has a stroke. Before making any changes to the shapes, make sure the Dimensions Include Stroke Weight and Adjust Stroke Weight when Scaling are DESELECTED in the Transform panel options. Make sure both the Info palette and the Transform palette are visible so you can read the starting and ending measurements in both palettes. Using the selection tool, select BOTH circles together, and then pull on any corner to enlarge the two shapes together. 3) EXPECTED RESULT: the two shapes should scale together. They start with the equal measurements in both the Info and Transform palettes, and once scaled, the shapes and the measurements should still read as being equal (albeit larger) sizes. 4) THE ACTUAL RESULT: the two shapes are different sizes after scaling. Remember that Dimensions Include Stroke Weight was deselected, so the stroke shouldn’t have any effect on the shape size, and yet, the bottom shape is slightly bigger than the top. Not only is the blue circle now clearly visible and peeking out from beneath the red circle, but the Info and Transform palettes read TWO different sizes. The following are images that illustrate the bug:

When i drag and drop a Textframe my Screen flickers black for a second - almost every damn time. This happens for me and most of my colleagues and it is horrible to work with.

I feel like it got worse after installing the latest "Tablehead" fix that fixed the disapearing tableheads.

Build 12.1.0.56
OS X El Capitan 10.11.6
iMac (Retina 4K, 21.5", 2015)
3,3 GHz Intel Core i7
16 GB 1867 MHz DDR3
Intel Iris Pro Graphics 6200 1536 MB

2nd Monior is a DELL U2414H, 23,5" at 1800p

This is happening on quite a lot of machines in my Company and also for Persons i know using a 4K Retina iMac. and Really is a pain to work with. - It is NOT visible in a Screenrecording the only option would be to record a Video from my Smartphone if needed...

Thanks!
