My aerial view appears to contain a "rogue" item that does not appear on my plan. The item is some distance from the main plan and consequently causes the aerial view to be "zoomed out".

The item appears on the left of the aerial view, so zooming out on the plan doesn't reveal it, as this only shows white space below and to the right.

I've also tried cutting and pasting everything, but that hasn't helped.

Has anyone had a similar experience and found a way to resolve it?

Thanks for any help.
