I have to experiment with this a while, since I don't use a whole lot of folders. Support was excellent and we discovered that it doesn't work with the add-on Thunderbird Conversations which the jury is still out on .
Support can be obtained by email to autofile@europhages.com or at https://europhages.com/autofile/help.html
The addon works fine with V128. Did you try desactivating all other modules to check the cause?
