Ambrosia Master Writ requirement doesn't match its description

On the Master Writ, it says to "craft a Psijic Ambrosia", yet when you accept it, it wants you to craft 8. Perhaps a bug due to the fact that it normally asks 8 for the purple food writs? The writ is only worth 10 vouchers so I can't see why they think people would blow 8 Ambrosia on 10 vouchers.
