Setting ButtonL1, L2, R1 and R2 on any volume up keybinds doesn't work

Just like the title says, it doesn't work at all. Idk why but when I set L1 in any other key in volume and the game things it's volume down still and now I can't hear the songs at all

The same thing happened to me, I changed the language of my roblox and it was magically fixed
