I need to track a friend and when I try to track their name the message "Already being tracked" appears but the name is not on my list.

When I try to add a friend to the tracker it says "Already being tracked" and the name does not show up in my list.

I am trying to track a friend with Platinum Tracker HUD but the dialog box says "Already being tracked" and the name does not show up in my list. Can one person only be tracked by one other person?
