Objects move away from Basepoint with Move Parameter (and they shouldn't)

[ColinPearson]

Hello World.   

I've used all the swear words I know and this block still won't behave!

 

When I use the Move grip and pull this block all the way up, it should extend by 5-7/8" ... instead it extends by 5-3/4" and also moves 1/8" from the Basepoint.  Any clue what's going on here?

 

Thanks in advance y'all!!!
