LoL Esport Pick'Em

So I have ben following up on all the games in the 2015 championship. And decided to play Pick'Em. But when it later was updated to the quater-semi and final pick'em. I did only move my choosed teams to the semi final as I thought that when the quater was played we had to choose semi final and then the final at last. But that dosn't seems to be the case as I can't choose what team I'll put my bet on. So now I'm gonna miss the last points that I could hav been rewarded. That's fair that it was made like that, but I can't find any place where it stands how I should've been doing it. So is there anything that can be done from here? Or was that just the last shot for this year? I would love to get t icons, atleast... Or does Riot handle this poorly from now on-?
