Moving leader back from submit files won't work

Description

I saw this by chance while testing LDEV-5143.

So if you have a submit file without groups and leader selection, if you try to move the leader back in the progress and delete the files she added in submit, then you get an exception and nothing happens.

However, this does not seem to occur if submit is grouped (see video).
