Hi,
The setting in your screenshot is the default setting for when you create new menu items. For existing ones, you have a display setting for custom fields directly under the "products options" tab of the menu item when you edit it via the Joomla menu manager.
Note however that these settings are for custom item fields. But on your other screenshot, I can see that these are custom product fields. And in that case, it's only the frontend products listing display setting in the custom field which dictates whether the field should display or not on the listings of the frontend.
