Hi @mark6 - Thank you for letting us know. Could you please try again with the latest client? We did some enhancements in this area for our 6.5.X release.
Also, it doesn’t appear correctly in the print dialog (pages are appearing partially off screen - see the white space at the bottom of each screen in the attached image), but when I export to the PDF it does look correct.
Thank you for posting, @mark6! This sounds like it may be a bug. I’d be happy to open a ticket to have this behavior investigated further. Before doing so, could you share a screenshot of the default value you’re seeing for the CSS you’re looking to modify? If possible, could you also share a screen recording of the behavior you’re experiencing, along with the steps you used to get it to work as expected?
