Travel Man season difference TVDB and TMDB
TVDB's Season 9 is TMDB's Season 8.
That's just based on the episode I was looking for. I'm not sure how many other seasons are wrong.
As best I can tell, TVDB is correct because the official website seems to back it up.
Unsure how best to handle this situation
Please open a support ticket if this is still an issue including links to the Trakt listing and as many details as possible. Thanks!
