[Client] Team Builder not Rewarding Icons upon Completion

I don't know why I can't anymore earn icons while playing in Team Builder.

I have earned the marksman and fighter icons already. I have recently been working to earn the assassin icon, playing more than 5 times already. I tried playing as tank and there is still no tally (1/5 wins, for example) when I return to the homepage after a game.

Has the rewarding been disabled or something?
