Steps to debug:

1. Add 2-3 items as Favs.
2. Restart the Application. Check if it shows those items as fav after restarting application .

Solution : Use another field to check if the data is added to fav.list

Delete will not work either Try

@Query("DELETE FROM favoritelist WHERE title = :title")
void deleteByUserId(String title);
