This show is now once again in active production. The new seasons are not reboots or reimaginings of the show: they are deliberate continuations of the original show headed by its original creator. Netflix added titles such as "The Return" and "The Gauntlet" for marketing purposes but they are referred to by the production company as seasons 11 and 12, and the new independently produced season as season 13. I have included evidence of this in the links below. I am well connected with the fandom and can assure you, despite the decades-long gap between seasons 10 and 11, this is considered a single show within the same continuity and should be merged into a single entry.
