HELP PLEASE! How do I undo a bank reconciliation?

[Cotton I Sew]

I added the date of 21/03/2031 instead of 31/03/2021 and my bank has reconciled to 2031! I now can't reconcile any further transactions for the financial year (I'm in Australia). I did search through the forum but the suggestions didn't work. I can only get a reconciliation in excel format and it has no date of reconciliation to adjust. 

My computer runs on Windows 10. Program files are saved "C:\Program Files (x86)\NCH Software\ExpressAccounts" but it only contains the launch files .exe nothing else. 

Is there anyone that can help please?

have you try this option?: 

Rollback to Previous

This button allows you to undo the last reconcile for the selected account. You may want to rollback if you have done a reconciliation by mistake or you have received more transactions that should have been included in the last reconcile.
Please note that this button will only be enabled when there is a valid reconciliation to rollback to and you will only be able to go back at most one reconciliation.

I’ve rolled back but the date was still there, hence the request for help.
