(not gamebreaking but just anoying) Lulu bug

So i've played about 3 games of lulu in the last 2 days now and in each of them i've had this happening to me. When ever i casted my E as lulu on an ally i could still hear pix's basic attacks as if i was attacking. No matter how close i was. It's just anoying, nothing gamebreaking or anything, but i thought it was worth mentioning.
