Yasuo Wind Wall doesn't block Annie Q

I was going up against an annie as yasuo, when i engaged on her. As i was disengaging, she sent a q towards me, i wind walled it, but it went straight through it. We both flipped out in the chat, very confused as to what happened, and we agreed to test it again. we set up, she sent her q towards me and it went straight through the wind wall again. there was no question about it not hitting the wind wall, it just went straight though it. needs to be fixed
