Folder View - not working correctly

[tritor100]

I have a complete tagged music library.

System runs at Proxmox Container and Media is stored on Truenas.
I tried varipus options of Jellyfin 10.10.7 and 10.11.4 always the same scenario.

All Albums across all folders are in general listed correctly if displaying "Album"

The folder structure looks like that:

---

music
 - Concerts
   - Cirque Du Solei
     - Alegria
       - Cirque Du Soleil - Alegría - 01 - Alegria.m4a
 - Deutsch
   - Ben Zucker
     - Na und die Sonne
       - Ben Zucker - Na Und!! Sonne! - 01 - Der Sonne Entgegen.mp3
 - English
   - Abba
     - Abba 18 Hits
       - ABBA - 18 Hits - 01 - The Winner Takes It All.mp3
 - Fimmusik
   - 2001 - A Space Odyssey
     - 2001 - A Space Odyssey - 01 - Various - Also Sprach Zarathustra.mp3
 - Folklore
   - Al Di Miola
     - Casion
       - Al Di Meola - Casino - 01 - Egyptian Danza.mp3
- Italian
  - Adriano Celentano
    - Super Best
      - Adriano Celentano - Super Best - 01 - Il Ragazzo Della Via Gluck.mp3
- Kabarett
 - Die 3 Spitzbuben
   - Das Best von
     - Das Beste Von Die 3 Spitzbuben - 01 - Die 3 Spitzbuben - Schönen Guten Abend.mp3
 - Sampler
   - ABC of the Blues
     - Volume 1
       - Abc Of The Blues - 1 - 01 - Kokomo Arnold - Backfence Picket Blues.mp3

Now the folder view of Jellyfin recognizes as folders only the folder "Deutsch", "Italian" and "Kabarett".
All other folders are listed I guess as Artist.

If I add each folder under music as a seperate library, all is displayed correctly. But that is more complex and Albums are listed seperatey / library.

Any solution here?

thank you
