This is intentional. Some mods who are trying to enforce badly designed rules because their database can't handle the complex reality of TV Show metadata.

In case you are using Plex you can go to the show, then Edit -> Advanced -> Episode Ordering where you can tell it to use the correct episode ordering from TheTVDB or IMDB.

Well, Hello to you too.

No i don't use Plex, I use FutonCritic, IMdb, TVmaze, TVdb, Wikipedia, AlloCiné, and none of them have the episodes 7-12 in Specials.

(and I use Trakt, hence my message, because they use TMDB data)

Episodes 1-6 are Part 1 and 7-12 are Part 2.
