PCB/CES desync issue deleting plane assignments?

 I am getting the following errors whenever I try to back annotate my design, and it's deleting some of my plane assignments every time I try:

Error: Problem encountered while synchronizing the layout data and schematic connectivity data in the Common Database. See PCBLogFile.txt for details. Loading of the database has failed.
Warning: Some of the layout data for this design conflicts with data being loaded from Constraint Manager. Some constraints may not be loaded properly. See the logfile 'ces_load.txt' for details.


 The ces_load Logfile contains 10 errors in this format:

ERROR - Constraint Manager Electrical/Physical mismatch:  Constraint Manager pin 'R1234-2' is referenced by Constraint Manager electrical net '$6N3484', but the pin's physical
 net reference in Constraint Manager, 'SOME_RANDOM_NET', does not belong to this electrical net.


The PCB LogFile, in it's entirety, states;

Xpedition Layout Version: 120.0.1610.4971

Successfully read the design.

Please forgive my ignorance, I've been doing this for 6 years, but what am I looking at here? We are running VX2.6.


Thankyou in advance!
