There are specific attributes for ricardo like title, subtitle, description and condition. You can find them when editing a product in the catalog. You will find a tab called "Ricardo", there you can set specific content for ricardo.
If they are empty, default values from Magento product will be used, only subtitle will stay empty for non-configurable product type.
