Unfortunately, the filters preference file (named "user_filters.xml") is not currently being packaged with the backup files. I have put a fix in place for this, but if you've restored a library backup, that file is most likely gone. As far as why updating caused the filters list to disappear, it's because my change to not automatically persist filters causes the list not to be populated correctly. If you enable Settings->Library Settings->Automatically Load Last Used Filters at Startup, then your list will be populated correctly. I'm working on putting an update together today, so the fix will be included with that. I apologize if you lost a lot of filters though - hopefully it won't take you too long to recreate them.
