I bit confused utilizing order status and state. I have created Delivered status but unfortunately it get duplicated with two different state. When I rename order status lable of anyone it will automatically affects others also so I am not sure which status is shown in frontend. I am also tried to unassign but it will throw error can't unassign already orders are used this status.When I change the order status to delivered that order is not listed in customer account page, but I need to show delivered status in customer account page.
