Symptom: Duplicate records in Aged Balances - Customer Credit and Collection workspace.

Resolution: 

The Product Group (PG) team has confirmed that this scenario aligns with the intended design of Dynamics 365 Finance & Operations. A customer record is expected to have only one Primary address at any given time. Therefore, the system is functioning as designed for this support ticket.

We recommended the following resolution options:

• Option 1: Manually disable the Primary flag for each address.
• Option 2: Add a temporary address and mark it as Primary. This will automatically reset the Primary flag for other addresses, after which the temporary address can be deleted.
