SOLVED: Wrong season and episode number metadata for several seasons of a show.

[nothingveryobvious]

I have all 34 seasons of The Amazing Race, plus the currently airing S35.

I know for sure that a few months ago, all of my seasons showed up fine on Jellyfin web UI and on Kodi. Now, only on Kodi, almost all of the episodes for seasons 1-16 are thrown into a "Specials" folder; the other seasons, 17-35, are totally fine. The seasons still look fine on Jellyfin web UI.

On closer examination I found that the NFO files for the problematic episodes have data that says the following:

• <season>0</season>
  
• <episode>0</episode>
  
• <airsbefore_season>0</airsbefore_season>
  
• <displayseason>0</displayseason>
  

For the problematic episodes/seasons, all the other metadata like date released and even the episode descriptions seem to be correct.

I tried replacing all metadata for the entire show, but the problem persists.

How is this possible? Is this a Jellyfin error or is there possibly something wrong with TheTVDB? Would it be worth contacting them? I don't want to edit the NFO files manually, especially since I'm afraid they might just revert back to the wrong metadata.

Thank you for any help you can provide!

It sounds like something changed your NFO files (probably not jellyfin). The NFO files will override any attempts to have external metadata sources correct this mis-labeling.

I deleted the NFO files then rescanned and everything was fixed! Strange. I wonder what changed them in the first place.
