Instead of submitting deletions, I would encourage you to try submitting corrections for the credits instead (as the credit may belong to a different person with the same name).
I did that but what happen was when the correction of the name was submitted the wrong spelling of the other name was never deleted therefore everytime there's a new credit for that name both names the right spelling and wrong spelling get credit. I can't seem to delete to wrong spelling of the name
