As explained in this previous report, they are not seasons of this show, but separate shows. Each one has its separate page on the Shudder website.

Feel free to create the series that are missing.

TMDB returns 4 separate shows for Joe Bob

The Last Drive-in with Joe Bob Briggs The Last Drive-In: July 2018 Marathon The Last Drive-In: A Very Joe Bob Xmas The Last Drive-In: Joe Bob's Dinners of Death

AMC+/Shutter returns 15 but only 13 show up with 'The Last Drive-in with Joe Bob Briggs' & 'The Last Drive-In: Joe Bob's Dinners of Death' being on both TMDB & Shutter. The remaining shutter results are

The Last Drive-In: Joe Bob Ruins Christmas The Last Drive-In: Joe Bob Saves Christmas The Last Drive-In: Just Joe Bob The Last Drive-In: Joe Bob Put A Spell On You Valentine's Special The Last Drive-In: Joe Bob's Halloween Hootenanny The Last Drive-In: Joe Bob's Red Christmas The Last Drive-In: Joe Bob's Halloween Hoedown The Last Drive-In: Joe Bob's Haunted Halloween The Last Drive-In: Joe Bob's Ghoultide Get-Together The Last Drive-In: Joe Bob's Heartbreak Trailer Park Valentine's Special

Per your reply these are separate shows however in TMDB's The Last Drive-in with Joe Bob Briggs episode list (S1-S4) there are 53 instances where the same episode is listed differently on Shutter's The Last Drive-In: Just Joe Bob S4-S11 episode list. Additionally, within the separate shows on Shutter the episode 'Ice Cream Man' shows up in 3 different shows

So from my perspective I don't have a lot of faith in Shutter's database and would prefer to use TMDB for my source of truth. I did create separate lists from both TMDB & AMC+ Shutter in .txt & Excel formats, I was going to attach them to this post but there doesn't appear to be a way to attach files and pasting raw data in this window is not practical. I would be happy to share them with you using another method if you would like, just let me know.

The KING is the Shudder website. The series should be created on TMDB as they are listed on the Shudder website.

All is explained in the previous report.
