Hi,
Try adding a Basepoint parameter to the block in the center of the circle or else you could recreate the block with the center of the circle as basepoint to eradicate this issue.
And another tip. Use the command "SELECTIONANNODISPLAY" and set it to "0" to make the different scales set to the object not show up when you select the objects. It would be quite annoying while modifying the object🙂
