What is the best way to collect Primitive Components in specified point?

Hello. In my game I need to collect all Primitive Components placed in specified location. I tried to use OverlapMultiByChannel with small sphere as CollisionShape, but in some reason overlaps for Primitive Components that fully contains my “point shape” are not generated.

I tried different radiuses of shape greater then KINDA_SMALL_NUMBER. Overlaps appeared only for Primitive Components that are fully placed or crosses my sphere shape.

So, my question is: what is wrong in my method and if there any more efficient ways for solving presented task?
