Kennen Ult and passive not showing up on screen

So i was playing a normal game as Lux with the Star Guardian Lux skin, and was laning against a Kennen with the Swamp Master Kennen skin. When we both hit 6 he went all in, and killed me, but I could not see his passive mark around my character, and his ults animation was not on screen, i could hear the visual ques for it, but it didnt apear on screen. This happened twice.
