I have a client that is using CRM 2013's Connector to push bi-directionally with GP.  (GP Accounts -> CRM Customers and vice versa)  They are cleaning up duplicate Accounts in CRM by using the native Merge feature.  The problem is, that it creates a "Secondary" Address ID in GP with all blank information.  The Primary Address ID is correct, but why is it producing a "Secondary" blank Address record in GP and how do I stop it?
