I was doing some research on this and found a temporary fix that seems to be working. This video walks you through it, very simple and the program has a free trial. Essentially you set a keybind and it locks your mouse to your primary monitor, and just hit the hotkey again and you're back to normal.

Im going to use this method until I can figure out how to fix the problem without the need of a program.
