I may not have understood you correctly, but I tried this:
Created a folder “TEST”. Moved a couple of programmes from the top level of the folder structure and two series folders (at the same time) to the folder TEST with no problem. Moved them all back to original place with no problem.
I don’t get an acknowledgment that the items have been moved, only that they have been “added for move”.
If I’ve understood you correctly, I can’t repeat the problem.
