Hi CAREYFIRSTNAT
This is likely not something you will be able to sort out over a forum, even with proper replies.
It might be best if you have a chat to your bookkeeper about bank reconciliation and the role it plays in having accurate accounts. There is something wrong if you have reconciled to Apr 2023 and there are Nov 2021 transactions 'not reconciled'. Without closely examining your accounts, while it is easy to 'hide' this, it is impossible to tell how to 'solve' this.
These are either duplicate transactions (which means your financial statements for that period are likely to be incorrect) and should be deleted, or the transactions were posted to the wrong account, or there is a corruption in the file relating to bank reconciliations.
Regards
Gavin
