Box collision component and particles

The easiest way to describe the problem is to refer to
Blueprint Quickshot: Triggerable Light | 01 | v4.7 Tutorial Series | Unreal Engine - YouTube the Triggerable Light (v4.7) tutorial.
I tried the steps in V4.8 Engine and all worked perfect. HOWEVER I noticed, being a first person shooter setup, the bullets or particles would bounce off the invisible Box collision component no matter what adjustments I made to the collision options.
Static objects, like the cubes in the scene, would pass through the Box collision component with no issues as well as the first person object (allowing me to pass in/out to toggle the light to go on/off)
Any way to allow the particles to pass through as well?
