That's exactly what I used to see in those forms before the issue was fixed.

You said you have updated ProSeries but let's make sure you really have the latest updates.

If you look at these files in Windows explorer:
C:\ProWin20\32bit\fsdk.dll
C:\ProWin20\32bit\fsdk_dotnet.dll
these files should have a "Date Modified" of 1/28/2021

Also look at:
C:\ProWin20\32bit\PDFPrinting.dll
this file should have a "Date Modified" of 12/15/2020

Do your files have these dates?

If YES, tell me what printer are you using (make and model) and I'll keep digging.
