Champions Tab

So I was looking over my friends profile (hehe ik im stalking him) And I saw the "champions tab" was not grey'd out so i clicked on it. It showed all his masterys and everything just as if it was my own. I went to another friends to see, and it was grey'd out. Now every time i check its grey'd out.

Is there a way to fix this? Or did i just get a lucky glitch?
