I've noticed there're 3 episodes on Amazon.

According to Wikipedia, the particular one you mention in your header is a film from the creators of the TV series. See the article at the link:

It‘s not really a movie. On my BD they are 3 individual episodes. They should either be part of season 3 (because they are the ending of s03) or specials

The film is presented as three 45 minute episodes. (from Wikipedia)

-> 3 episodes not one movie

Even presented with 3 parts, this is originally a theatrical movie that is listed in the movie part of our database.
