Bank rec - out of balance value cannot be located.

Hi, I was catching up on my bank statements until a month of Oct/Nov 23 where I was out of balance therefore could not reconcile yet all transactions and closing balance entered were correct.  I worked my way backwards on undoing the bank reconciliations to 30/6/2023.  When redoing the July 23 reconciliation it is still out with the same value from Oct 24.  I do not want to undo any further bank reconciliations as each month is the same value and nothing was edited or deleted prior to 30/6/2023.  How can I move forward and reconcile my bank when I cannot locate the out of balance value?

Thanks, Kim
