Multi Currency Option Error for Manufactured Prod

I have set default currency to my company as USD.

I have created a few manufactured products by defining the unit price of each (currency could not be selected for products)

Then I add those products in the customer order.

When I create invoice against the shipment, on preview it displays the actual price but when PDF is exported seems like unit price get converted to USD based on defined local currency. But the product price entered is USD.

Could someone help to sort out?

Got to see a bug in order sheet as shown below
