Audiobooks not recognized

[Drakon]

Hi everyone,

i downloaded a audiobook of a game over Steam, which comes chapter separated in both mp3 and wav file format. Since i didn't used the audiobooks feature of Jellyfin so far, i figured i might try it.

Added a new library, followed the structure and naming conventions as laid out here: https://jellyfin.org/docs/general/server/media/books/

But sadly, it doesn't appear to work very well... Jellyfin recognizes the chapter wav files seperately. When i click on the books library, it brings me into a folder view. I can navigate down to the folder where the chapter files are, but it looks like this:

   

I googled some and found out that i didn't had the "bookshelf" plugin installed, so i installed it, restarted Jellyfin and triggered a full re-scan of the library. But nope, no luck. 

Am i missing something? Is perhaps using "wav" files not correct? Or is this just how Jellyfin supports Audiobooks currently? I can technically play them, but it looks very weird and the sorting is also all over...

Installed is Jellyfin 10.10.3 in docker.

Thanks in advance
