XR Device Simulator thumpstick no (0,0) input event

Hi all,

I use from the XR Interaction Toolkit 3.0.6 the XR Device Simulator, but have the problem that i only get events from the Thumbstrick for (0,1) or (1,0) but no event on (0,0) input.

I subscribe to the InputActionReference event from the “XRI Left/Thumbstick (Input Action Reference)”:

public InputActionReference thumbstickInput;
...
this.thumbstickInput.action.performed += OnThumbstickInput;
...
private void OnThumbstickInput(InputAction.CallbackContext context)
{
    this.anchorMoveInput = context.ReadValue<Vector2>();
    Debug.Log($"OnThumbstickInput: {this.anchorMoveInput}");
}

Does someone know a solution?
thanks in advance
