GAMEPLAY riven q sound when q'ing onto a target doesn't make the sound on battle bunny riven skin

on the battle bunny riven skin when using q on a minion or champion you can not hear the q sound, all u hear is the grunt that riven makes when she charges her q, so its the same sound as when your just randomly using q getting to lane or walking somewhere. this is really weird because it works on all the other riven skins its just battle bunny that has the problem.
