I’m trying to finish grabbing a show, but Sonarr says the final season is #3, while the rest of the internet (i.e. torrent sites) says that season is #5. It looks like the first 2 seasons were split up into 1/2 seasons when originally shown. So while Sonarr is looking for Season 3, it’s finding the first half of what it thinks is Season 2.
Honestly just don’t use it for everything. Sometimes the Metadata isn’t good. That plus being highly opinionated makes some niche cases not suitable for sonarr
