Printing from Custom Reports to pdf problems

With the new version: 25.10.7.2906. Windows 11

Custom Reports - normal printing is OK.

Printing from Custom Reports to pdf is not working correctly. Can someone shed light on this please.

Print to pdf using the PDF button - formatting lines before and after totals are missing

Print to pdf using Microsoft Print to Pdf - background changes from white to light grey. Print a paper copy it is still a grey background.

I’m working on resolving this.
