Local Extras bug on Plex HTPC

Player Version#: Plex HTPC

There is a bug in PLEX HTPC when displaying Local extras on episode level.

I have deleted scenes on episode level. They are correctly showed on a Android mobile and TV. But on Plex HTPC extras are showed only for first episode of the season. If I select another episode in the season extras of the first episode are always shown.

There are no episode-level extras in HTPC.

So the bug is that Plex HTPC shows local extras on episode level for first episode of every season?

I couldn’t tell without seeing the files and folder structure.

This is the file and folder structure:

E:\Serije\Lost\Season 1\Lost (2004) - S01E01 - Pilot (1).mkv
E:\Serije\Lost\Season 1\Lost (2004) - S01E01 - Pilot (1)-1. Smoking-deleted.mkv
E:\Serije\Lost\Season 1\Lost (2004) - S01E01 - Pilot (1)-2. Chicken or Lasagna-deleted.mkv
E:\Serije\Lost\Season 1\Lost (2004) - S01E02 - Pilot (2).mkv
E:\Serije\Lost\Season 1\Lost (2004) - S01E02 - Pilot (2)-Kate and Sayid-deleted.mkv
E:\Serije\Lost\Season 1\Lost (2004) - S01E02 - Pilot (2)-The Climb-deleted.mkv
E:\Serije\Lost\Season 1\Lost (2004) - S01E03 - Tabula Rasa.mkv
E:\Serije\Lost\Season 1\Lost (2004) - S01E03 - Tabula Rasa-1. It’s For Vincent-deleted.mkv
E:\Serije\Lost\Season 1\Lost (2004) - S01E03 - Tabula Rasa-2. Finding the Tell-deleted.mkv

And this is what I see in Plex HTPC for every episode that has local extras:

It is always the same extras, and if episode doesn’t have any extras, then no extras are shown.
