For individual player's (Ratings History).
My two HD3 teams show potential. As does my one HD2 team.
You have to make sure you are logged in .. AND .. looking at your active team.
What I mean by active team is .. if you have the Team Profile page open, then you switch to a different world on the Main team pages, then the Team Profile page you had open (from the original world) is no longer your active team. So all players are average (as if you are viewing someone else's team .. you are actually, since you are viewing your team from another world).
To check this .. close all HD windows in your browser and reopen the main menu and look at player from your active team.
