Jellyfin displaying duplicate missing files for episodes

[Akeldema]

Hi.
Been struggling with this issue for the last few days, on a few select series jellyfin is displaying a duplicate missing episode for every single episode in the season.
       
When looking in the media directory there are no duplicate files or metadata.
       

I have tried refreshing the metadata for just the series as well as doing it for the full library, this has persisted through restarts of the server.
I have linked a log file https://pastebin.com/LtC1sFv7 , it is fairly large unfortunately, there do seem to be a number of messages relating to this series at the bottom of the log, but I lack the knowledge to interpret it.


Thank you.

Just my thoughts when I read this, but i have not encounter issue before.

I am assuming you have become familiar with the documentation on naming conventions for Shows.
https://jellyfin.org/docs/general/server/media/shows/

1st thing that seems odd to me is that you have 86 number & character eighty six.
What is the shows actual name? "86" or "86 Eighty Six" or "Eighty Six",
I can see that being a potential confusing name for the parser.

2nd thing that might need cleaning up, maybe the way you have episode
names appended, might be causing the parser confusion. "S01E01 - Undertaker".
Maybe Jellyfin is reading it as a part or a version.
Maybe try file same formatted such as "EightySix_S01E01_Undertaker",
assuming the folder structure follow convention, it should still know what the show is,
and if you still have issue, shorten it to "S01E01".

Good luck, anime is also where i seem to have issues with picking up correct metadata.

It's all named using the TVDB naming. as far as 86 goes, for 86 it does show as "86: Eighty Six" on TVDB.

I'll experiment with naming conventions, I would have thought if my naming using TVDB's names was causing problems it would have shown sooner, as its only a handful of series out of a few thousand with issues.

Numbers in show names throw off Jellyfin's file parser.

I have given up on pretty file names and have simpilied everything to reduce this kind of problem.

Library/Show Name/s01e01.mkv

No show name in the file name. No episode name in the file name. Just the season number and episode number.

Its not exclusive to shows with numbers in their name, as I had half a dozen broken series.
however i have had a bit of luck with a fix, if not a root cause of it.

Turning "display missing episodes" off in the user settings, Then deleting the meta data from the bugged series, doing a rebuild of the missing metadata and then turning the "display missing episodes" back on has worked for removing these episodes, I tried deleting the metadata multiple times both through jellyfin and directly through file explorer, but until I turned off display missing episodes first it never worked.
