trouble with phantom image in paperspace

my problem: when working in paperspace, a phantom image appears, which is not visible in model space. this phantom image duplicates part of the constructed drawing, but unlike the constructed drawing elements, i can not erase, move, nor determine which layer the phantom exists on--if it does exist on a specific layer.

possible clues:

1  there are two ucs icons in view within the viewport. One ucs icon seems to be tied to the phantom. i can turn on this phantom-related ucs icon, but doing this does not turn off the phantom.

2 the phantom image is visible when viewing the plotter's preview screen.

a related question: is it typical to have multiple ucs icons present in one drawing file? can or should one be deleted?

thanks
