Messed up my library?

[chainer]

Jellyfin is running in docker.
I've changed the mapped folder name in the compose file, Downloads -> Download and made a full rescan.
Now the actual library is missing from admin dashboard, and whenever I try to add a new one on the same path jellyfin prints there was an error adding the media path. please ensure the path is valid and jellyfin has access to that location. and just creates several new, none of which, naturally, watches files updates (doesn't add new media automatically)
       

The new library and the duplicates aren't present inside the container
   

and in the config folder
   

Any advice? Should I make a clean install or it's fixable?

Well, i've ended with moving all files to a new dir, passing it under a new value to the jellyfin and creating a new library. Now everything works, including monitoring of new files.
The only question remains how to remove unnecessary entries on the home screen...
