Foreign currency invoice shows AUD amount

We use Accountright with foreign currency enabled.

We recently upgraded to MYOB's new invoicing.  Since then I have noticed that when customers click on the new "View invoice" button when a USD invoice is emailed to them from MYOB, a summary at the top of the page incorrectly shows the amount in our home AUD currency. 

For example, we sent a USD invoice for USD$11,990 and the summary at the top of the page that shows when the customer clicks on "View invoice"  says INV-223920 for $18,330.53.

This is misleading and confusing for our customers in other countries and needs to be fixed please.  The summary at the top of the screen should show the amount owing in the currency of the invoice.
