Correction on RGB declined

I watched RBG the other day and I was cleaning up the credits as I watched. One of the existing credits is:


Limbaugh, Rush              Himself               (archive footage) (voice)

This seems wrong to me because he does not actually appear in video, just his voice. There is an (archive voice) credit so I tried to change it over to that and also note that he is uncredited. The change would be

Limbaugh, Rush             Himself               (archive voice) (uncredited)

This was declined but I'm not sure why if the original was accepted. Rush's voice is distinct enough and used in a way that anyone who knew would recognize the voice. If my correction doesn't meet the guidelines, then the entire credit needs to be removed.
