Bugged Level 6 Progression

Ok so, I get to level 6 and I'm presented with three champs to pick from, Illaoi, Riven and Garen, yet when I go to hover over them, I can't select ANY of them as the "select" icon vanishes when I go to click on it.

Is this a known bug or....?

FYI - This isnt a TFT bug, but for some reason I can't post to ANY other board than this for support? Ya'll bugged this too? haha.
