[Gameplay] Wrong audio on auto attack

I was playing a game as Shyvana with the Championship skin. On my team was Graves with the Pool Party skin. When I auto attacked the audio that played was not the Shyvana attack audio but the Graves Pool Party auto attack audio. I even exited the game, closed the client, and re-loged on, but the issue persisted. Below is a link to the game as there might be some other issues that caused it.
