I don't bother renaming files after I download them so they're left looking something like this:
[group] anime name - 01 [fileinfo] [crc32].mkv
This becomes problematic when you have shows like New Game, where the first is stylized as NEW GAME! and the second season is NEW GAME!!. Jellyfin shows them both as the first season of the anime, where as Plex with the Hama TV scanner can distinguish between them.
