A deleted filter keeps reappearing
On one of my IMAP accounts, I decided to delete one filter, as it appeared not to work. It went off the list. I then looked at other IMAP accounts, and returned to the first one: the deleted filter had reappeared. I had cleaned up the startup cache - to no avail, when Thunderbird restarts, that filter is listed in that account.
I am running Thunderbird 102.2.2 on a Windows 10.0.19043 Family on an Acer Aspire One 755.
