Additional Options-Structure

simple question – When I click on the “additional options” under the Structure tab, nothing happens. Is this in the Premium version or is something not setup correctly. Note: this is on multisite, on network active.

Will be looking to get Premium version- seems like great support and the plugin filters great on woocommerce site.

Thanks in advance.
