Yasuo Q Bug

Hey Riot, I'm a Yasuo main and there's a bug that's been really annoying me lately. When I stack up my 3rd Q and ult from someone else's knock-up (like a lee sin ult), it shows me that i sill have my knock-up available (from my third q) but when I use it, its a regular Yasuo Q and this messes me up when I'm team-fighting because I think that I have my knock-up when I actually don't. Thanks
