I'm having an issue where all expressions that have opaque backgrounds show up as solid black boxes after exporting as PDF.
They're in the exact same location and have the same dimensions/shape as the expressions. They show up properly while working in Finale. This happens whether I go through File>Export>PDF or Graphics Tool>Export Pages>PDF. Doesn't matter if "allow transparency" is checked or not.
Unchecking "opaque" for the individual expressions fixes it. Any border lines show properly, too.
I like using opaque expressions for items that need to go across bar lines without interrupting the text.
Finale version 18.104.22.1687 running on Windows 10 Enterprise.
