Warwick (Rework) Sound bug

Well i have been playing the new Warwick for a while, total blast but i noticed something strange. Upon using your E sometimes randomly i notice that i doesn't drop the Roar upon its activation and its been happening for the entire time I have been playing him, and i don't see any problems, i am just having issues with this sound and nothing else so my sound software is fine, i don't know what it could be. If you know maybe a possible fix or maybe its just because he's a new hero please tell me down below.. Ty
