Mail existing rules work, but cannot change any rules
In Ventura I had a Mail corruption and fixed it by reloading ~/Library/Mail/V10/MailData from Time Machine. Everything seems to work *except* that I cannot change any rules: changes disappear after quitting and relaunching Mail (but making a rule active/inactive survives relaunch).
How can I fix this?
