InputSystem.EnhancedTouch lose touch and see more finger

While using EnhancedTouch in a simple scenario, which is basically just

    private void Update()
    {
        if (Touch.activeFingers.Count != 0)
        {
            Touch activeTouch = Touch.activeFingers[0].currentTouch;
            Debug.Log($"{Time.frameCount} Touch: {activeTouch.touchId} AT {Touch.activeTouches.Count} AF {Touch.activeFingers.Count} - Phase: { activeTouch.phase} ");
        }
    }

Sometime I see up to 3 fingers active and touchID change frequently even if I use only 1 finger that never leave the screen.

Also I never see the Began phase or stationary

Anyone experience something similar?

I’m seeing similar things on 2021.2.16f1. This was not happening on 2020.3, any ideas what may have changed?

InputSystem package 1.3.0

@Morphus74 I just figured out the problem. The Input System Package settings in the Project Settings has an option of when the input events get updated. Mine was set to process in Fixed Update and since I was checking input in Update() that did not pick up all the events accurately. Changing the setting to process in Dynamic Update made it work for me.
