CMYK Black is shifting to gray upon export after updating InDesign 19.5.2
I'm working on some files that have tone on tone colors, and last night when I exported my PDF everything was fine. Today I updated my software to version 19.5.2 and suddenly my black is shifting to gray upon export. I've checked output, removed everything from the surrounding artboard, removed all RGB colors from the swatches. When I export PNG everything is as it should be, so this is solely a PDF export issue. All other colors seem to be normal as well, only Black is shifting.

Could you share a sample document with us?
If yes, pl. put the same at a shared location (like Dropbox, etc.) and share the link with us.

Hi, here is the packaged file for one of these projects. The 100% black shapes on the back are all shifting to gray when exported and on the front all but one shape is shifting to gray instead of black.
