No buy button when gallery is placed on a page

Dear Image store

Love the look of the plugin, I have one issue. I have created a gallery, I have made a price list, I have added the gallery to my page (Photography), I can view the images  as a lightbox popup(looks great!!) but there is no buy button, and there select unselect and all those type of things on the page. Please what am I doing wrong.

I am using a child theme of BoostrapWP,

Here is a link to the site:  http://rookdesigns.co.uk/?page_id=10

Thanks in advance
