Bug - Overprint not working correctly
I have noticed colours not displaying correctly when overprinting. It is happening on images, blocks of colour, everything.
It seems that Cyan won't overprint Cyan. Magenta won't overprint Magenta. Yellow won't overprint yellow.
I've tried all the colour profiles but that doesn't help. I have created a pdf from InDesign to illustrate the issue. The stars point to the incorrect overprints.
I believe it is also happening in Illustrator.
I updated my apps hoping that might help but I have the same problem on the latest versions.
I've working in printing for a long time and this seems like it might be a bug.
Using Indesign version 20.1.0.

I'm also having huge problems overprinting several process colors.
It's a straight CMYK book with no spot colors, so i'm using multiple overprints to add color depth (within 270%).But, InDesign seems to have lost the additive values and knocks out each plate beneath with the overprinting values...? I've tried various things but can't achieve accurate over prints without disturbing the color beneath!
I need help on a workaround as I have a deadline in 5 hours!
