How to delete a "library"

[Hanu]

Background:
1) I tried to install Jellyfin to my Synology NAS using Container Manager. Installation failed. 
2) Installed Jellyfin with SynoCommunity package. Installed ok. Works '~ok'.

Now I have a library named 'Kansiot' which I cannot see or delete in Libraries. Maybe it is a remains from 1)

Anyway, how can I delete library 'Kansiot' ?

Do you have folder view enabled?

Thx, Folder view was enabled.

How can I rename 'Kansiot' to something else? I cant find this anywhere.

I should have put "Kansiot" into Google translate.  Would have saved the step of asking if you have folder view enabled.  

No, you cannot change that name since it isn't a "library".  If you don't want this "folder view" you'd have to disable it.
