Yasuo windwall bug

Ok so i was playing against as yasuo vs yasuo the other day and i had the upper hand, i landed more q's and everything. We both got our tornados and i used mine first he windwalled it and i was like "ok ill just do the same" and when i did it to his it went legit through my windwall. And dont think i just messed it up. Messing up a yasuo windwall to a slow projectile like that will never happen and same has happened to Moe (Yassuo) multiple times and it's still not fixed
