I’ve read the Forum about the TVDB vs. Trakt issues, but One Piece has also duplicated episodes with slightly different names and number typology.
I’ve even disconnected Trakt to try and fix it, but the duplications are still there.
Please. Help.
To completely remove duplicates you would have to remove the show and add it again. But note that all your watched episodes will be gone as the new data source (TMDB) numbers them differently. So you would have to mark them again.
Also syncing with Trakt will currently not work as they number episodes like before (still using TheTVDB as a data source).
Sorry that there is currently no true solution for this.
