Jhin Mark Visual Bug

So, I was playing Jhin today, and I seemed to run into a visual bug. This Fiora on the enemy team had the mark overlapped many times, and it seemed to not go away, as seen in the picture. I'm not sure why this happened, but i think it was something to do with her parry, since it happened right afterwards. The next bug was similar, but it wasn't overlapped, it just the mark didn't go away. The enemy Ziggs had my mark even though he didn't get hit from an allied champion recently. I hope this is helpful. Thank you. https://gyazo.com/313bbad5e61d7c015ecf89af4e2490c6 https://gyazo.com/39230275d59deaf632e6e17c1f629a74
