When I use the credit memo to refund customer and return the qty to stock the qty is not being returned to stock.
E.g. I have 1 hat instock I sell the hat and the qty changes to 0 and status to out of stock. However when I do a return to stock via credit memo the qty stays at 0 and status out of stock. It will not update the stock when a return is made.
How do I fix this?
