Incorrect currency is shown in Woo orders page

Hi there,

Thank you so much for this plugin, a really great one and works well for us.

However, I can see that the transaction for an international order is being shown in the default currency in the Woocommerce orders management page. For instance, a buyer from Australia bought an item for $150 AUD but the transaction is showing as $150 USD in the backend in the orders management page (USD is the default currency in Woo settings). This messes up the accounting and reporting for sales for our case. Any workaround on this one or am I missing something?

Thank you!
