Jellyfin displaying wrong season titles for One Piece

[TheDreadPirate]

One issue I see is that every episode is named "One Piece". If you want to keep [AnimeRG] in the file name, it is best if that is at the END of the file name. Having it at the beginning might be throwing off the file name parser.

I also suspect there will be a conflict between your having season folders, but also using the absolute order in the file name, but then want the episodes grouped by their story arc.

What metadata source are you using? TMDB provides the season order, absolute order (no seasons), and story arcs for many shows. If you "Edit Metadata" for the show there is a drop down to select which order to use from metadata source that support multiple orders (generic list of most common options, may not reflect all options available for some shows).

I'm asking around how you would need to get Story Arc ordering working if you aren't able to figure it out with the above tips.
