This Feature Request was fulfilled on November 29, 2018 in Platinum Version 3.3.0

when i refund credits to customers and go to the customer my orders page. it shows the refunded credits with $. where in it shouldnt have $. and also the totals dont match. But the credits have been refunded back to the account. its just that its not represented correctly on the customer side when they go on to the orders page
