Just removing "Rated" prefix at the beginning would suffice.

The MPAA rating has the whole sentence, ie: Night Crawler
MPAA - "Rated R for violence including graphic images, and for language"

But, if you put USA at the top, then you would only get
"R" or "Rated R" (depending on selected option).

I'd leave MPAA structure alone, as some prefer this. If your only wanting the actual rating, ie: G, PG, R, R16, then move MPAA down the list of IMDB Certificate Priority
