Trouble exporting Script to PDF

Hi Guys

I am working with Version: Beta (1078406) 64-Bit - 14 Okt 2020.
When I compile my script to PDF (Script/Screenplay Setting) most of the written text comes out as gibberish. Just radom letters. Some are correct - but most of it looks like this:

When I compile the same Text as “Rich Text Format”, everything looks fine.
Any Ideas?
Thanks and stay healthy!
