Re-import From/To List Under Route Harness Does not Work

Hello, I'm suing Solidworks 2013 paired with Solidworks Electrical 2013 to do some harness work, and I have come across an unfortunate problem.

Using the Route Harness Command >> Re-import From/To List does not have any affect on my harness.  I have already routed the entire harness, and the routes all look very nice.  If I edit the 2D schematic in Solidworks Electrical 2D, apply these changes to the harness and then go back to Solidworks 3D, and use the Route Harness >> Re-import From/To List, the harness remains unchanged.  Deleted wires show up as gray, and they can be removed, changed paths and added wires do no show up as new routing guidelines in auto-route as I would have expected them to. 

Any help on this matter would be wonderful, thank you.
