Admin is the only one listed on v4. Some of the older OS version had root and administrator all under the admin group.

Change owner to root or to your self. All users is like a guest which in some cases prevent a single user from deleting it. Then restart the server, to force the change to take place. But only after waiting for 5 min. Rebooting before the owner takes place is what I did that lost it.

Make sure the share is empty.... Clear of all files and folders.
