Deck card description not saving

I am on Nextcloud Hub 7 28.0.3 and over last few weeks I have noticed that I am not able to save a Deck card description. It will occasionally work but 90% of the time it does not save. Upgrade to 28.0.3, sever reboot, and fixing database missing indexes has not fixed this issue.

To help figure out where the issue is, on the top left corner of the card where it says “Modifed: xx ago” - what does it say?
