When using Export for Screen to Export PDFs, the blacks are messed up.

Attached, you see a picture of the two PDFs opened in Edge. The left one is saved with "Save a Copy…” command. Right one is exported with Export for Screens utility.

Every time I open Illustrator, half of my workday goes in debugging this kind of annoying things. I so much hate Illustrator.
