Corki audio bug

Just played a few ARAM games against a few Corkis and couldnt help but notice that when after he uses his E (machine gun) after the animation stops you can still hear the sound of it going off. I don't know if it's just me or what is happening. Unfortunately since this is my first time posting here I didnt get a video of it... If its just on my end I would love to know how to fix it since its really annoying... Thanks everyone!
