Message notifications won't clear because they blocked me

I was playing with a random in rush. He sent me 3 quick messages then blocked me. Now every time I change screens I have 3 message notifications but I cannot remove them because he blocked me. If I open messages the notifications go away but the next time I change screens (whether I go from club to play or sbc's) the message notifications come back. Is there anyone who knows how to make them go away?
