Can't delete empty ghost library

Hello,
I am looking to delete a ghost library, which no longer has content, which belongs to a “user” department that I have not created. I do not have the possibility of deleting it properly.
The seaf-gc.sh script does not resolve anything and the seaf-fsck.sh can’t repair script.
Has anyone ever encountered this problem? would you have a lead to indicate to me.
I am using Seafile Pro 7.0.9 with AD and a mariadb database
thank you in advance for your help

Johann

The library should be able to delete in version 7.1.
