Bug in role queue beta. Invalid class forced

Hi, I’ve made my 15 classification matches in role queue beta.
My last role was healer. Now every time I choose the role i want to play it forces me to play as a last role I was classyfiyng (healer). I can’t play as other roles to boost my SR in classes other than heal in comp. This bug didn’t exist on PTR, where i could play as role i wanted.
