"In progress" only shows the top 8 champions

So the champion master on the profile is great and all but the second page that shows the champions you have points for currently only shows the top 8 champions that you have points for.

I'm pretty sure this isn't intentional, and hopefully Riot will fix/add this in the future.

(Also, does anyone know what happens when you have over 8 champions with Rank 5 mastery? Do the old champions get pushed back or will the first 8 you've mastered be forever on the front page?)
