Mordikaiser Kog ghost bug [GAMEPLAY]

So I believe this bug might just have to do with the skin he was using but not entirely sure tho. So in the clip you can see that when the kog became a ghost from morde ult it was having issues displaying the proper skin for the champion witch is battlecast but it is trying to also display pugmaw as well making some sort of horrid abomination between dog and machine.
