I see many comments in these threads about how to recover a reconciled transaction that was deleted in error.  In my situation the transaction was not deleted in error - it was a duplicate transaction and needed to be deleted - it should have been marked as unreconciled before deletion, but was not.  The transaction was a transfer between 2 bank accounts.  The second of the duplicate transfers has been matched to the bank feed and cleared.  What are the steps to clear that error in the opening balance when there is no transition to restore?
