Music stacks when moving between menus

When my menus starts at first it should find that music isn’t playing and start it (setting the variable to true) then when going back to the main menu from settings it should find that the variable is true already so not begin playing again. And yet it still stacks the music every time I re-open the main menu. This may be a rookie mistake as the variable is clear when moving between menus and I have to place this in-game instance but I just don’t know what to do.

here you can see that the only reference to playing music is in this blueprint


Here you can see my BP where the issue is located

You have two bools with the same name. One if each menu blueprint.

You need to use just one. You could put it in the game instance.
