Toggle music button inconsistently working

I have this minor annoyance that has been bugging me on and off because it’s one of those things where one day it works, some days it doesn’t.
So i haven’t changed the keybindings for the toggle sounds (ctrl + s) AND the toggle music (Ctrl + M) buttons but sometimes while waiting/alt tabbed i just want to shut off the music but keep the rest of the sounds up just in case so you press the toggle music button and to my surprise the screen prompts that it functions as “Disable/Enable sounds” but some days i press the same button and it actually works and will display “Disable/Enable Music”. i do not know if an addon is causing it because i dont have any keybind changing/sound controlling addon.

TLDR sometimes the toggle music keybind also becomes the toggle sounds as well and you lose the functionality of turning just the music output.
