Warning: This may look like it “works” for you in Season 04, but it’s kind of a red herring. When you turn on “Absolute ordering”, Plex uses that naming scheme from TheTVDB - Dragon Ball - Absolute. In that scheme, all episodes are listed as if there is no concept of “seasons”, so it just lists all numbers from 000 to 153. However, it still “TECHNICALLY” is season 1, which has all episodes. If you go to Season 1 in Plex, you see if was able to download the metadata for those episodes, but the “rest” of season 1 is missing (because you put them into other seasons). So it looks like S01 has info, but the rest are filled with generic no-metadata listings via “Episode 1” and “Episode 2”.
Unfortunately, TVDB and TMDB do NOT always match their numbering systems to that of “official” show wiki lists. With Wikipedia, wikia pages, TVDB, TMDB, fan pages, etc; It would be impossible to support all those (possibly) different numbering scheme. So Plex only supports TVDB/TMDB number systems. As I said earlier, the only part of your episode file names is the “SxxExx” in the name. It ignores EVERYTHING ELSE about the filename, and simply matches that number versus the online database you specify (TVDB/TMDB). If you try to fight Plex on this, you are going to have a bad time.
Bizarrely, I cannot seem to get the Dragon Ball episodes to display the English title when I look on TVDB in season view. I have to click through to the episodes themselves, where I see that S04E01 is “Who is Fortuneteller Baba?”, which you see in Plex.
This is the source of your “problem”. Your Plex is pulling metadata for episode data from TVDB, and that does not match your numbering system. If you wish to “correct” this, take it up with TVDB. I don’t think they’ll change anything here for you, but it IS a site based on user-submissions. An old show like this is probably fixed in stone at this point.
FYI, a free file renamer program I use and suggested by others in these forums called Rename My TV Series can help you quickly rename your files to work in Plex. Otherwise, you may have to edit the metadata on all the Plex entries MANUALLY, which will suck royally.
