Why do out of balance reconciliations have an unidentified difference of zero when you open them?

We have some accounts where the View Reconciliation List shows the Unidentified Difference as having an out of balance.  However, when you open the actual reconciliation, the unidentified difference is zero.  Why is there a disconnect and how do we get the Reconciliation List to properly show the unidentified difference?

Thanks in advance,
