Some order statuses are applied when a particular action is performed, while others need to be manually applied. For example, Order processing will change an order's status to Processing, whereas a Cancelled or Declined order status has to be manually applied.
To manually change an order status, select it from the Bulk action drop-down on Dashboard→ Orders→ Bulk action
