Cannot add more than one operation rep if they've all been deleted

[BCerki]

Describe the Bug:

Go to the operation rep page, add some op reps, delete them all, and try to add more. The first one will work and then when you try for a second, nothing happens. If you refresh the page, everything's fine and you can add them again.
