I am sorry if there are answers to this, but having searched I can only locate solutions referring to unauthenticated maps (with no distinction).
I have several maps installed and in Mapsource they are all unlocked. They load to my device without a problem either. However in Training Center they are shown as Unauthenticated and display BaseMap detail only.
You have to navigate to get to the good.
