[GNC] Budget reporting issue

[Robert Stocker]

I've just run my budget report for the first time since the 5.0 upgrade
(specifically, I'm on version 5.0, build ID Flathub 5.0-1, on Ubuntu 22.04
LTS ), and my saved report configuration comes up completely blank. In
troubleshooting, I find that if I use the "Make PDF" button and export the
report as PDF, it is fine. Reporting here to see if anyone else is having a
similar issue.
