It says "Mastery Chest" in exactly one spot in the client, and it's likely a string they forgot to change.

Why are you "testing" stuff that has been tested over and over on PBE, Live (TR) and Live (NA) for the past few weeks/months? I mean, the boxes you earn from mastery grades stack with the ones from the shop (aka they're the same thing). That alone should be a dead giveaway.

As for official Riot documentation and testing. You double check everything and note the differences. You shouldn't have to report behavior that is working exactly as expected (and already covered by the general info on the page).

The page was in a sorry state before I started editing it, it's still missing quite a bit of info but it's at least covering some of the more basic things.
