A manual credit note is used when you want to cancel only a partial amount of the invoice.
If you need to cancel the invoice for a booking/extra, you should rather reopen the account in order for the system to automatically pass the credit note.
Remember that when you reopen an account after an invoice has been generated, the system will automatically generate the invoice for you.
