Updatable order statuses

-- url of the page with the problem -- : demo.hikashop.com/

Hello Jerome,
i still don't understand how it works Updatable order statuses ;-(

Orders authorized for modification in the front-end ??

demo.hikashop.com/administrator
Updatable order statuses > empty

demo.hikashop.com/index.php/en/hikamarket/vendor-control-panel
Orders Page > click it on the order number > Click on the button Edit status... and change the status of the order!?

Explain to me.

Now the list is full. I see no difference ;-(
