How do I restrict the influence of Force Field to the Collection it's in?

I'm trying to simulate falling leaves in Blender 2.8.
I have a Collection with the Leafs_Emitter particle system and a Vortex Force Field inside it.
I want the Force Field only affect or influence the falling leaves inside the Collection.
But currently, it affects all the other particle systems inside my scene.
