Initial Reconciliation

Hi. I am trying to reconcile cheques that were unpresented at Conversion. I have followed all the steps (several times!) but my reconciliation is out of balance by the total amount of the unpresented cheques. My opening balance on the account is the balance as of the Conversion date. I have entered the cheques as per instructions and I have a deposit and a withdrawal for each cheque. In the reconciliation screen, I tick the deposit for each cheque but it's out of balance as described. The calculated statement balance is $430.00 (the total of the cheques) more than the Closing Statement balance. What am I missing? Thanks, Anne
