Futurama season numbering is messy and inconsistent. In some places the movies are counted. In some places, the aired ordering of episodes is used. In other places the dvd release order is used. I think there’s some seasons that were aired in 2 separate parts, so in some cases those are considered 2 seasons, or 2 half seasons, or 1 season.

Since both Plex and Sonarr use thetvdb, I tend to use that as the source of truth as well. And according to that site, s8e10 doesn’t air until end of September.
