[GAMEPLAY] Kayle ult always on!??

I had this bug in game where an enemy Kayle ulted her ally bard and the ult visually stayed on him the rest of the game. It tilted me so hard because in my mind "Kayle ult means don't focus the ulted person you wont do damage." This visual glitch also occurred in every single other person game so I was not alone. This glitch needs to be assessed. The link is to the replay of the game. It happens around the 14:15 mark where kayle ults bard, bard then takes a magical journey, and then is stunned as he exits the journey and the kayle ult remains on him thoughout the rest of the game.
