I tried for some reason when configuring buttons dont want to register. For example I have controller 1 setup as wii u game pad on controller 2 the only options you have are classic and pro controllers I tried both didn't work.
You can only set one Gamepad. Can you tell us more details about how you configured the other controllers?
Are you unable to set the buttons you want your other controller to use? It doesn't let you import/export controller configs? It won't save it?
