Custom season artwork does not work

Since TMDB does not have a season poster for the TV series "Bon Cop, Bad Cop (2026), I try to setup my own .JPG but it does not work. I am using Infuse 8.4.5 in Libray mode and accessing my video files on the NAS via SMB protocol. Here is the structure of the files on the NAS:

Bon Cop, Bad Cop (2026)
  Bon Cop, Bad Cop Season 1
     Bon Cop, Bad Cop.S01E01.mkv
     Bon Cop, Bad Cop.S01E02.mkv
     etc...
  Folder.jpg
  season-all-poster.jpg

Folder.jpg is correctly displayed as the series poster. The “season-all-poster.jpg” file is not displayed in infuse as the series season poster. According to the “Overriding-Artwork-and-Metadata” help section, it should work. I am not using any streaming connection. I tried naming it "season 1-poster, but it does not work either.

What am I doing wrong ?

P.S. Refreshing metadata does not make it work either.

One thing I’ve had cause problems is when you have the year in the series name but not in the episode file names. Maybe try

Bon Cop, Bad Cop 2026 S01E01.mkv

(Do that on all episodes)

Also on the individual season folders it looks like you have

Bon Cop, Bad Cop Season 1

as the folder name for the season. That will cause problems too. Use just “Season 01” as the folder name.

Thank you very much NC_Bulleye, it worked.
As suggested, I renamed the season folder “Season 1” and added the year to each episode, refreshed the metadata and TADAM!! Success

Best regards.
