The main episode list reflects how the series was originally broadcast. There are additional episode groups which reflect other orders.

I see the other episode groups, but for the episodes listed on TVDB, season 6 is missing and season 7 has taken its place. Benders big score, The Beast with a Billion Backs, Bender's Game, and Into the Wild Green Yonder are season 6 but have been moved to the "Specials" group. IMDB has the correct airing order.

As indicated by Rebecca, we list the episodes as they have been originally broadcasted.

As you can see on this archive of the official Comedy Central page, the last 2 episodes "Stench and Stenchibility' and "Meanwhile" were broadcasted as season 7.

It is of no use to compare with the listings of other sites as each site has its own set of rules.

I understand that your site is different and that why you exist. My problem is that you've excluded these 4 episodes that make up a season: Benders big score, The Beast with a Billion Backs, Bender's Game, and Into the Wild Green Yonder. Depending on the scheme you're following, they should be season 5 or 6. If you're following the dates alone, then these comprise season 6 since they aired between 2008 and 2009. Season 5 is 02-03, Season 6 is 08-09, and Season 7 is 10-11, Season 08 is 12-13, etc. My big point is these 4 (or 16) missing episodes and that Plex sucks.

They are not excluded, they are listed as they were released, aka as special episodes and are consequently listed in the specials season.
