Hello, Whenever I restart Thunderbird, it opens my inbox with an old filter from a search from several days ago (possibly more than a week ago even...) showing up. This filter was inserted several days ago and I have cleared it multiple times on the restart, but it still keep popping up on any new TB restarts. I have used other filters to search many times since the one that keeps showing up, and they do not replace that one on restart. The filter I used was in the inbox main filter window (not the global search on top). The filter was for "tw" without the quotation marks. I have tested doing other filters and exiting TB with the other filter still in place, but still it's the old "tw" filter that shows up on restart, not the new one. I am running Windows 7 Ultimate sp1, 64 bit and Thunderbird 91.4.0 Thank you!
