Controllermap recognizes one d-pad button as two

I’m not sure if this is the right place for this, but I’m having an issue with the controllermap test tool.

I have a Wireless Xbox 360 receiver with a wireless 360 controller connected to it. I’m trying to use controllermap to get a mapping for my controller. The tool works fine until it gets to the d-pad ones, where it asks for left, down, right, up in that order. When I hit left on the d-pad, it somehow gets two inputs and returns something for down as well. The same thing happens when I hit right, up gets registered and it moves on. Is there a way to fix this?
