How does something like this get fixed so it can be synched?
Also of note, the episode numbering on TMDB is not different than TheTVDB and Trakt, I used the Fandom Wiki episode guide since what is on TheTVDB and Trakt is a mess with duplicate episodes and a few other issues.
Please open a support or help ticket or click the Report Movie/Show/Season/Episode in the left sidebar of the Trakt.tv listing and share as many details as possible in the notes field.
