Yasuo Wind Wall Bugged?

I'm just curious. I'm not sure if it is supposed to happen but Twisted Fates wild card stun continually goes through my wall time after time, game after game. Is that supposed to happen? P.S. Sivir Q and several auto attacks went through my wall as well. No I did not deploy it late, not they weren't on the side. We stood in the middle of the lane and tested it and i got stunned by TF and autod by Sivir... through my wall.
