Data correction for the show Detentionaire
The season 1 is only 14 episode but trakt show 27 episodes ! https://trakt.tv/shows/detentionaire
TVDB indicates 27 episodes in season 1.
The problem must come frome TVDB then, because episodes 1x15 to 1x27 are the same as episodes 2x01 to 2x13 (wikipedia also says that season 1 is 14 episodes only)
