Verdant arena

I don't see any reports on this for NA yet, only EU. But the new verdant arena isn't showing as available when you unlock it. Clicked on the button to "loot" it, but it's greyed out when you try to select it in the game lobby. Not sure if it has anything to do with the fact that the name in the game lobby is "Basic Verdant Arena" and the name of the unlock is just "Verdant Arena" But that's my theory...
