Age rating arcade

So when I check the arcade, It only shows games with a rating of E. But I have recently learned that there are other games of higher rating, like T. But as much as I tried I can't find a way for the arcade to show these games. How could I show other games with higher age rating than E. (T and up)

RPGninja please don't create multiple threads for the same topic. I've locked your other thread in How Do I as a duplicate.

There are only two ratings allowed, E and T. All games of these ratings are viewable by everyone as far as I can tell.
