I believe we have addressed this concern in your ticket but correct me if I'm wrong. With that being said your new 6.0 screens should all look like this for shipping.
UPS, Fedex, USPS, etc all got a bump up in terms of UI and you no longer have to configure them in the Advance settings section. All "Custom" aka non USPS, Fedex, UPS, are now listed as "Offline". These are the old method of shipping providers through this screen such as shipping by weight, etc.
