Make Jellyfin use original air date?

[Backwoods Genius]

You should have been able to just "replace all metadata" after removing the NFOs.  Next time, you can also try removing the folder from your library, scan to remove it, re-add the folder, scan to re-add.  Sometimes metadata becomes "sticky" for no explainable reason.

I don't know what to tell you, I tried every variation I could think of. I deleted everything except the video files, I corrected nfos manually to see if it would update correctly, I removed other metadata sources, I "replaced all" metadata... everything came back mixed up. If you look at the nfo I posted above, that is not the correct tvdbid for that episode. Jellyfin clearly knows what episode it's searching for since it pulled in the correct thumbnails. So maybe something's wrong on the backend of tvdb and it's spitting out the wrong ID number. Or maybe the listing on the webpage is wrong. I promise you that manually editing 100+ file names was not my first thought.

I will try removing the folder before I continue the editing process. I'd been wondering if it wasn't some sort of cache issue and that seems like a good way to clear any caches. Thanks.
