I have installed the plugin to comply with the local tax laws, that part works fine but when used with a coupon code it produces two very different invoices.

The one it sends out is faulty in that it shows the full amount and listed as unpaid, this however is wrong and should read as paid as is shown on the admin site invoices section under transactions.

You have 2 completely different invoices being issued for the one transaction, the email copy being wrong the transactions copy being correct ? unless I am mistaken.

Please video of both version for the one invoice number 75.
