For some reason whenever I cancel an order, after payment, before shipping, the cancelation returns one less than the total to stock. If one was ordered and the order canceled the stock is not adjusted up by one, if 10 were ordered and the order canceled 9 are returned to stock!
Similarly If you issue a credit memo with the setting “return items to stock” the stock is not adjusted back up.
Has anyone else encountered or noticed this before?
Any help or advise would be very much appreciated.
