Master Yi "R" Sound With Kayn's "E" [GAMEPLAY BUG]

So for a while now there has been a bug when I activate Kayn's "Shadow Step" or "E" ability while there is a Master Yi on either my team or the enemy team, and it is really annoying. Basically what happens is that the sound that plays when you activate Yi's "R" ability will play when using Kayn's "E". Usually the sound will stop after "Shadow Step" is finished its duration, but sometimes it plays a couple seconds afterwards, or even for the rest of the game the sound will keep going. So far as I can remember it has happened every single time I play Kayn and there Is a Master Yi on the enemy team or my team. (Unconfirmed, but from what my friend has said, when he plays Master Yi and I play Kayn, is that he can also hear the sound going on on his end as well, I am not sure about this though.)
