Integrator-to-XC Sync Issue

Good morning,

I’m running into an issue when I sync wire information from
an Integrator plane to a harness in XC where some wires “lose” one connection
point.  So then, after running design rule checks I receive numerous
“unconnected wire” errors.

This happened last night, so I went back into Integrator
just to double check the wires and they contain both end points on the
plane. 

Now, here’s the deal (and maybe the culprit, somehow)…

When I sync from Integrator, I am only syncing wires, into a
skeleton that was created by syncing from the Integrator plane.

Any ideas as to what I might be doing wrong?

Thank you!
