Please provide any additional information below:

I previously had a similar problem when configuring the DualShock 3 with 
NullDC, with registering correct commands from the controller, which was 
corrected after posting here.

Attached is an image when the corresponding buttons to the image are pressed, 
and what results in the plugin menu.

dpad is consider HAT buttons on Dualshock 4 in Windows control panel. All 
functions detected by Windows control panel and other emulator plugins 
including PCSX2's lilypad controller plugin.
