[Gameplay] Yasuo - q visual effect not working correctly

With yasuo when having two stacks at your q, meaning the next q will fire a tornado, and you ult from an ally knockup the stacks get depleted (yes I know this is intended to happen). But the problem is that the circle around yasuo, indicating the range of the 3rd q, is still there although your next q will be a normal one, like 1st and 2nd cast. Only by firing a tornado again will the effect be gone

1. charge your Q two times, so that the next one will be a tornado
2. have an ally knock an enemy up
3. ult this enemy without using your Q --> result: you have no Q stacks but the visual circle is still there

You can see what I mean in this video. (if not linked correctly, go to 5:58 :)
