XInput D-Pad and Triggers not working

Because Unity doesn't let me read controller axes the same way I can controller buttons with GetKey/GetKeyDown, I was pretty much forced to use its default input manager on this one.

The thing is, for whatever reason my left stick works perfectly fine, yet my D-Pad and Left/Right Triggers don't work at all. I'm using a HORI Real Arcade Pro 4 Kai which works perfectly fine in literally any game with XInput Support (Tekken 7, Street Fighter V, Dragon Ball FighterZ... really any game with XInput Support) when using the D-Pad and Triggers.

For the d-pad, I'm using Axis 6 for Horizontal and Axis 7 for vertical. For the triggers I'm using Axis 9 for LT and Axis 10 for RT. Even trying to Debug.Log(Input.GetAxis("axis name")); doesn't work, where "axis name" is the copy/pasted name of the axis I'm trying to access, of course.

I've also tested this using a standard XInput controller and the problem persists. Is there something I'm doing wrong?
