Duke controller not working correctly?

[IDrinkLava]

I'm trying to use the Duke controller with the McBazel USB adapter and Xb2XInput, but it's not working correctly. The left analog stick only registers diagonal up-left to diagonal down-right, while the right analog seems to map random buttons to various directions. Pressing A also causes very slight left analog down movement for some reason. My Type-S controller works perfectly fine, so I don't think it's a problem with the drivers or anything.
