Can't move DiscID?

Release Alles was added without tracklists expect of disc 17.
Copied original release with disc 17 of the release above to add tracklists.
Aim was to merge releases then, but this don’t work (because of missing tracklists).
Now I’m trying to move the DiscID to a new copy, but MB don’t let me do this. I get this message: “The data you have submitted does not make any changes to the data already present.”
I’m sure I have done this before.

Any hints?



Thanks!!! @chaban
