Gallery not removing from album

What happening is that the client remove the last gallery from the album and even though it the album is still showing an empty thumbnail container. If you look at the source code you’ll see empty tags as well.

Hope you can see this before the client creates a new album in efforts to remove a legacy thumb and code.

The url is http://cristallgallery.com/artists/

Any ideas other than just starting over would be greatly appreciated.
Thanks
