Sound bugs

Hey y'all!
So I wanted to report a bug regarding the sound. Often, when i play Pokémon games, i tend to leave in-game sound off and play music or something or the other. So, I went to Options and set Sound Volume and Music Volume to 0. It muted most sounds, but some stayed. It mutes background music and the "check" sound, but a handful of sounds remain, such as the Pokécenter healing sound, the sound after an evolution and the sound after winning in the coin slots. These are the few that I have encountered so far. Any help is greatly appreciated.
Thanks!
