You may need to do custom code to show your custom order status on the frontend in both order list and order details.php.
When you will add new order Status for WooCommerce you need to use the same filter to ADD NEW CASE to show and save the 
order status when someone updates the order and to send order status changes through order-notes on the frontend. 
Kindly use the below hooks to get it done.

dokan_get_order_status_translated & dokan_get_order_status_class


Kindly open dokan-lite/templates/orders/listing.php and check this filter- dokan_bulk_order_statuses which should help you.
