Gamertag used to show profile name, now just shows "Player"

Up until about a month ago, my gamertag was in sync with my profile name.  Then it suddenly changed to "Player".  Running wsreset occasionally changes it back, but it doesn't stay and reverts to "Player".  Reinstalling the game did not help.  Running the game from the launcher changed it back once, but now does not do it any more.
