Hi Amy5
Thanks for your post. The Closing bank statement balance is the closing balance on your bank statement and the Calculated closing balance is the last reconciled balance plus transactions ticked in the Reconcile accounts window. Deleting or changing previously reconciled transactions will change the Calculated closing balance and affect future reconciliations.
To work out what is causing the out of balance you will need to follow the steps in this Help Article: Fixing out of balance bank reconciliations.
Please let me know if you need further help.
