IMDb allows someone to add a credit that is identical to an already existing credit except without the "uncredited" attribute

I pointed this out 7 months ago and it is still happening. I went through all of Peter Rotter's credits on several shows and marked them as uncredited as he has never been credited on any show that I have watched. Now, the duplicate credits are back. You can't see them from the name page until you edit it but it is obvious if you use the field browser and he has twice as many credits as he should have.

Can a staffer clean this up again, removing the recently added duplicate credits that already exist with an "uncredited" attribute. Editing his page is a nightmare because there are so many entries. Also, can you reach out to the contributor that keeps adding them and telling them to not add them. Also, hopefully a change can be made in the software to reject these additions if they already exist while ignoring the "uncredited" attribute.
