Custom Field Shortcodes Not Working in Tabs

Hello.

I have the premium version.

I’ve chosen the tabbed page layout for products. I’ve created 2 custom fields. I’ve followed the directions to add the short code for the custom fields to the tabs.

The shortcode displays. It doesn’t not pull in content.

Here’s a link: http://qem.wpengine.com/motors/?&SingleProduct=8 See the Specs and Options tabs.

Please help.
