Input dispatches 3 times instead of 1

Hi guys,
I handle input through PlayerInput and UnityEvents, so I have a handler for the mouse click. This handler is invoked three times (each time for one phase), but I've setup interaction "Press Only".
Should it be like this, so it means that I have to filter it like

Code (CSharp):

1. if (context.performed) {}

or this is a bug? (Input system 1.0.2, Unity 2020.2.4)
I've tried a dozen of variations for "Interaction", but currently it looks like this:

 

I am having the same problem with keyboard input.
