Music volume slider doesn't turn off music

Are you turning down the music slider AND clicking the "Ok" button?

I'm having the same issue.
Every time I restart the game,
the music is playing.
Slider bar stays all the way to the Left at 0%
(No "OK" button),
but music still plays.
Moving slider to the right,
then back left to 0% silences the music again.
Until the next time I restart the game.
Music playing with slider to the left at 0%.
(I'm using a Galaxy Note 9)

This was supposed to be for Minecraft Earth.
