I removed both Season 2 and Season 3. The original anime has no season: http://www.tv-tokyo.co.jp/anime/cap_tsuba/story.html

What is registered as Season 2 episodes 1 to 7 must be S01 episodes 20 to 26

Do you have a source for a release with two seasons of 26 episodes?

Not actually; but a lot of 80's and 90's anime is not ordered in "Seasons" as eastern TV shows yearly batches of episodes define them, instead, they group their storyline as "sagas" (see Dragon Ball Z or Saint Seiya) that are aired back to back, and yet, they are marked as seasons on TMDB. That's why I suggested Season 1-2 ordering. For archiving and ordering purposes, i also think absolute order should be used, rather than fake-season order used on TVDB, or trakt, for example. Thanks for the correction, of course.

Alright, thanks. The reason I was asking is we can create any number of alternative orders with the episode group feature. So creating a group with two seasons wouldn't be an issue. I just need to know what I'm creating (a TV group? DVD? Digital? a made-up order?).
