Arduino Leonardo USB - USB Joystick Lib Question

I am using the USB joystick lib from Matthew Heironimus on a Leonardo. It works great. My question is regarding how Windows sees the device. When I set the joystick type to "joystick" or "gamepad" in the code, Windows identifies the device and I can see the axes and buttons in device manager for testing. When I set the joystick type to "JOYSTICK_TYPE_MULTI_AXIS", the device is seen as "Arduino Leonardo" and I can't see the axes and buttons in device manager. It still works, I can go into a flight sim like X-Plane and use the axes and buttons. Just wondering what prevents Windows from identifying the device the same as the other 2 types...

Thanks for any ideas!

The library can also be downloaded directly using the following: https://github.com/MHeironimus/ArduinoJoystickLibrary/archive/version-2.0.zip

#include <Joystick.h>
