PDF export result different between two documents with identical page
Hello!
Once again, I have a more or less weird effect: an address on the last page of a PDF exported by Indesign results in an odd display in Acrobat, but only in one document of many that use the same last page design.
Correct PDF result:

Weird PDF result:

The text in those boxes is identical, all with identical format settings. I even copied the affected text box from the working document to the one where the crap comes out and put it in the same position. Of course, I use the same PDF export dialog and settings. No matter what I tried, it always comes out as such. No clue, what happens here and why.
Thanks for any idea.
Addition: going into edit mode in Acrobat reveals something.
