Today I tried to look up a previous email that I'd filed in a subfolder, but the folder displayed no emails. If I click on the subfolder above it, it shows me the number of emails and displays the list of emails. Then when I click on the subfolder I want, it displays the name and number of emails for the previous subfolder I looked at. I tried troubleshoot mode, but still no luck, and the folder is gray instead of yellow like all the others. I'm using Thunderbird 115.9.0 (32 bit), Windows 11 Home 64-bit. I've been using Thunderbird for years and have never had this problem before. Hoping someone will have some advice!
