Phantom Block lines in technical view

Hi, I see this issue in my files and cannot find a solution.
I build an object and then insert it into a file as a block. When viewing in “technical” display mode, I will see phantom lines where the block originates. I don’t see these lines in any other display modes…

See the following images:
1- wire frame mode (pay attention to 0,0,0):


2- technical mode (arrow highlighting phantom lines)
block object on all layers

it may be hard to discern but there is both a square and a round form that each represents a carton and a bottle shape.

Its easier to see on the layouts:
wireframe


technical

see block manager and properties here:

How can I manage the blocks to avoid this odd behavior and eliminate the lines?

thanks,
John
