Inconsistent Collisions with Objects

Hello,

I am having trouble getting the collisions right on some of my items.

The “Box Collision” I have on an actor is having inconsistent responses when I need to “Get Overlapping Actors”

Actor A - A static mesh with physics that contains a Box Collision

Actor B - A static mesh with physics

Any reason to why when I run a command to “Get Overlapping Actors” with the “Actor A->Box Collision” I am getting inconsistent results?

Thanks for your help,

Much Appreciated
