[Gameplay] Champion Mastery/Experience Not Showing

At the end of my games, I can't see how much champion experience I gained. It just gives me a loading circle and spins forever. Although, I am able to see my updated experience when looking at my profile.

Here are some photos of the issue: http://imgur.com/0i3MVs4 http://imgur.com/A5MxdpG
