Game doesn't recognize the switch Pro controller, but the rest of my apps and games do

The game has the buttons all scrambled and doesn't recognize the A or R buttons. The Y button is actually the L button and the triggers are actually recognized as RB and LB. The left joystick button(LJ) is actually the Select button, RJ isn't even usable, and the screenshot button is actually select. The home button is Start. + And - don't do their job(start and select, respectively) DPAD works fine, and so do the joysticks themselves. I recommend adding a more customizable control mapper to the game itself. It'd save so much time and money, instead of locking us down to just buttons 1-20. A good example of a customizable controller mapper is the one included in Dolphin Emulator.
