Code showing on Product Page

Each product page shows this code between the Description and the Options:

slide_template: default
sbg_selected_sidebar: a:1:{i:0;s:1:”0″;}
sbg_selected_sidebar_replacement: a:1:{i:0;s:1:”0″;}

I have cleared cache, switched to Twenty Fifteen Theme, Deactivated all non-eCommerce plugins and cleared browser cache. Still get the code.

Any ideas why it is appearing?
