Can you try deactivating and reactivating s2Member? Be sure to enable Deactivation Safeguards first: WP Admin -> s2Member -> General Options -> Deactivation Safeguards.
Also, you might want to try deactivating s2Member, deleting the plugin, then re-uploading the s2Member files to your website.
The problem you're describing should not happen. The custom fields are designed to appear on the Pro Checkout forms, so if you don't see them there, then something is either wrong with your installation of s2Member or a strange configuration issue on your server (less likely).
