I have registered an order to a provider who list all their prices in USD, however, at the time of payment it will be made in the local currency according to the USD rate of that day.

At the time of paying the supplier invoice, I used the "Change currency" button to set the value to the local currency, and all the values got correctly updated. However, when looking at the "purchase orders" dashboard, it is reported as if invoiced 1200% ... Have I done this wrong, or is this a bug related with the convert currency button for purchase invoices?
