Brawlers Bug

I won 2 games of brawlers, clearing the first requirement to receive the icon so I move on to the next requirement. I won six games, all of which I hired different brawlers and won. However, it still claims that I'm missing a brawler. So I win a few more games, still nothing. I've grown tired of the game mode because of all the lag that comes in late game with all the brawlers stacked together. I just want the icon. Can someone look into this? Thanks.
