[Gameplay] Zed shadow keeps disappearing

I was just playing a match of One for All as Zed and I found about 10 minutes into the game that my shadows from my W would disappear, mostly after I used my E. The strange thing was it wasn't like the normal expiration because i still had the status effect from the shadow being out it just wasn't visible and it would not respond, or if it did i couldn't see it.
