The item being marked 'unordered' is for our internal ordering system.
It is the default status of all items when an order is first placed.
When the item says 'unordered', it has not yet been updated to the next status. These status updates will be backorder, split order, deleted or ready to dispatch.
As the order is being processed, the status 'unordered' will change to one of the mentioned statuses where applicable.
