I just posted the tracker MDL-58697 about this issue.
Hope we can get some insight on how to solve it.

We have also experienced this at least twice now so have voted on the issue in the tracker; we're on Moodle 3.0 at the moment moving to 3.2 soon.

I've come across this too in version 3.1. I'm fairly certain that we have made changes to the assignment after the first files were uploaded by students. So perhaps there is a connection.
As only a few were affected I changed the submission status in the database directly (mdl_assign_sumbission table).
