Ummm this is not coming from Super Orders. My guess is that you've installed Edit Orders v1.55. From their changelog:
9. Prevented deleting of orders with 0 products.
If the order has to be deleted this can be done on the orders page.
For this the installation instructions changed and a new button was added.
If the order has zero products the button changes from 'edit' to 'add product' and then takes you to the
add product page instead of the edit page.
