Book Balance in Bank Reconciliation

SOLVED

Our bank has not been reconciled in Sage from 2018 onwards because of some issues. Now I want to start reconciling in Sage. Our bank balance is as below and there is a book balance of the below amount in the picture. The question I have is where is the book balance coming from as the Trial Balance also shows the amount that is in the bank. Where is this book balance getting the amount from as I have cleared all outstanding transactions also within the bank reconciliation.
