While trying to edit hitpoints i got this message
Never seen it before (I edit a lot)

Now I cannot do my job (few days ago all was working well as usual)

Latest C12, latest MacOS on M1 MBP

UPD: rebooting and disabling prefs helped but after next launch with saved prefs I’ve got the same issue

What do I need to fix in prefs instead of deleting them?
