When using "mass-edit" of albums, if you try to apply a "guest user" & "password" to multiple albums the setting is not saved to any albums. I tested "Allow Comments" & this setting was saved to multiple albums.

If you try to apply "Album Password" setting individually the setting is saved.

If you are attempting this from a sub-album, you are returned to a mass-edit window at the top level of the gallery after applying, you are not returned to the album you were editing.

I also noticed that "Bulk Actions" are not available in a "mass-edit" which seems odd.

Please open a ticket.
