Classified Theme – not showing Amazon Buy Now button.

In the old version of Classified Theme, when you add a product using Amazon import. You will see the Amazon Buy Now button. This is an example.

BUT using the responsive Classified Theme, import a product via Amazon import. I don’t see the Amazon Buy Now button. This is an example
https://www.king.net/listing/rolex-submariner-green-dial-steel-mens-watch-116610lv/

How will I show (activate) the Amazon Buy Now button in Responsive Classified Theme?

Thank you in advance.
