The input value for the upper left is strange when using the D-Pad on an Xbox Series X/S controller

The input value for the upper left is strange when using the D-Pad on an Xbox Series X/S controller.
Is this a problem when using Unity’s Input System on a Mac?

I’m developing on a MacBook Pro.
I’m creating controls using the Input System. When using the D-Pad on an Xbox Series X/S controller, simultaneous input of left and up is not recognized.
With other combinations, a normalization of about 0.7 is added to one side, but if you press left and up at the same time, both values ​​become 0.

However, it works normally with controllers other than Xbox Series X/S.
The same phenomenon is occurring in both Unity6 and Unity5.

A problem with the controller? A problem with the Mac version? A problem with the Input System?
Or a problem with the script I’m writing?
