Thank you for sharing your concern here at the Community, @RayAdmin.
I'm here to help you correct your reconciliation in 2022 and provide you with insights about undoing multiple transactions in QuickBooks Online (QBO).
First, may I know if you've migrated from QBDT to QBO? If so, this might be the reason why you cannot see the reconciliation history even if the transactions have been marked as R.
The possible reason why your opening balance is different is that the account wasn't set up or with the right balance. It could also be due to voided, deleted, or modified transactions that were previously cleared and reconciled.
Furthermore, with regard to your concern about selecting multiple transactions to undo reconciliation, this is only possible if you are using QuickBooks Online Accountant. Otherwise, you'll need to manually undo the reconciliation for each transaction.
Moreover, I'm adding these helpful articles as your reference in fixing other reconciling issues:
