[2020] Mouse 4 does not work when using on Xbox one.

Not sure if this is appropriate for this sub but this problem only happens in this game. I am using a keyboard and mouse on Xbox one and I am not able to use mouse 4 for any command. It will show the command bound to the button but in game the command doesn’t work. I press and nothing happens, tried several different commands. Mouse 5 works fine. The button isn’t broken, I tested in modern warfare and it works. Quite annoying to be down a button that I am used to using. My mouse is a glorious model O. Anyone else experienced this or know what could cause it?
