It can really depend on your metadata source. For really long animes like, Detective Conan or One Piece, there are multiple ways to order the show. Some orders are very different. The way you have your anime ordered may not line up with the metadata you are currently pulling down. By default Jellyfin will pull down the "airing order" of a show. Go to TVDB or TMDB, whichever is your current metadata source, and check how the airing order is arranged and compared with how you have your files named and organized.
