product schema not working

Hi

First of really Great plugin! thank you 🙂

I’m using the latest version of WordPress, woocommmerce and Divi Theme, with a child theme enabled.

For me the plugin doesnt work on product pages, meaning that I do not have the ability to markup my product pages, via backend. There’s no ‘selector’ attribute (This guy here: http://take.ms/wRVm5, is not on the product page), when creating a product.

The plugin works perfect on posts and pages (http://take.ms/bmCW9)

The page I need help with: [log in to see the link]
