Grasp different objects with Pinch Utilities (LEAP Orion)

Hi!

I start to create a project with the new LEAP Core Assets 4.0.2 and Pinch Utilities v1.0.1. A want to grasp some different objects in Unity, but when I grab an object, I grab every object which is attached to LEAP RTS script. Anyone has an idea, how can I catch one object that others do not grasp?
