BigBox - Controller Mappings - "Awaiting Controller Input"

[AdamL]

If I go to Options -> Controller Mappings in BigBox and select an action to set (e.g. "Navigate Up", a window pops up that says "Awaiting Controller Input..." 

The problem is that it doesn't accept any controller input, so when I eventually hit back (ESC), the action is cleared.

How do I fix this and get it to accept a controller input?

I know that BigBox sees the controller (joystick) because "Navigate Down" is set to "D-Pad Down, Left Stick Down" and it does the navigation when the joystick is pressed down.  But now, "Navigate Up" shows as "{None}".

Also, why does it use "Left Stick Up" when the controller is actually labeled "Ultimarc Ultra-Stick Player 1"?  

Thanks!
