Exactly as @nickottino says. Every time I want to reorder the products one again, I have to start from scratch. After saving the product order and reopening the settings, the products are displayed alphabetically (even though they have the correct assigned sort numbers). However, any drag-and-drop of a product in the list causes the entire list to reorganize. Is there any way to preserve the product order after saving, so that when reopening, they appear in the previously saved order?
