Ward disable sound

When using either Sweeper, or a Control ward, sometimes the sound for them being disabled gets replaced by another sound. I just had a game where it was replaced by Jhin's Bouncing Grenade sound (there was one on enemy team, base skin). I recall having it happen before, but forgot to report it then (I beleive then it was either the same sound or Heimerdinger's stun bomb sound, I can't recall exactly).
