Impossible to change bank details on new invoices

I've added a bank account to our system but I can't make the new one the default on 'Bank details to display' when creating new invoices. I clicked on setting on the new account and made it default on the drop down menus but it's still displaying the previous one. I've also archived the previous bank account and that hasn't worked either. Please advise on how to make the new bank account the default one without manually selecting it with each invoice.
