center of mass symbol location incorrect?

Using 2017 SP 5.0, I have an assembly that I've been tracking CG, mass and inertia's since creation since this is a rotating mass. I'm at the point where I'm making a drawing to aid in balancing and I've created a center of mass symbol which is an option in the mass properties window.The center of mass symbol was not created at the coordinate location as stated by the CG mass props. After a long and tedious investigation I found that the hidden but not suppressed parts in my assembly were causing the shift. Therefore the center of mass symbol that SolidWorks creates uses hidden parts in the calculation and the mass properties table does not unless you check the box to include them.

 

My question is have other users found this to be true? I'm not sure I like this functionality especially when you can run mass props with parts simply hidden. At the very lest I'd like to see this explained in the help popup for mass props. I personally don't like keeping certain parts suppressed if I have active parts that are mated to them.
