How to position spheres that are created with the CC Ball action?
CC Ball is a video effect to make an array of balls that video can be displayed on.  It isn't designed for making circles that you can move around like this.  What you want is a 3D shape object.  Unfortunately, unless you have a 3rd party tool like Blender to make a geometry you can import, there isn't an easy way to make a true sphere in AE.  

The only real option I know of without using a third party tool is to take a period or circle shape layer, extrude it by its diameter and apply a curved bezel and adjust the strength until it results in a fully round sphere.
