[Client?] Free Champion Rotation Bug

So, I logged on today, knowing that the free champion rotation has changed. I bring up the launcher and see this. I'm thinking to myself " , , , , , AND free to play?!?! This will be awesome!" yet when I click on Darius I see this. I'm getting exicted because now I see , , , , , AND . But then I started wondering, which group is free to play? By the time people respond to this, I will probably have started a game and know who is free to play, so don't respond saying which group is free to play.
