Steam recently changed the default privacy settings for all users. This may impact tracking. Ensure your profile has the correct settings by following the guide on our forums.
If your profile is showing up as Not Ranked, please review our rules page and follow the appeal process detailed there.
Seems your profile is private, I can't view recent activity or game history. Go to Xbox.com > My Profile > Security, set See your game and app history (Xbox 360: Game History) to Everybody.
Once you've done that, your profile/gamercard should update within 6 hours or so.
