Wrong Linked Category used

Hi There, 

Previously, the asset category account for tracking receivables that was linked to it was a bank account. So probably that was why the bank account, instead of AR, was credited everytime an invoice is created even though I used income account in the invoice. I change the linked category to Accounts receivable, however, it did not update the journal entry on the invoices that were previously recorded. How can I update all the invoices that were credit to bank account without having to delete each one? Payments were already applied to these invoices. I am using MYOB online. Thank you!
