right stick x+ movement doesn't register

[CamboIsAwesome123]

For some reason, no matter how much i try, it won't let me bind anything to the X+ of the right joystick. If it helps, I'm using a Switch Pro Controller

Are you trying to bind the X+ axis of your physical controller or to bind the X+ axis of the virtual controller in-game with the advanced mode?
What OS are you on? Is your controller connected via bluetooth or USB and can you try the other way around?
