This is a user specific problem when a user removes and re-installs the Facebook App. The re-installed app will recognize the user as a new user, so there are two databases in conflict for the same user, the old database and the new database. Even the leaderboard is showing two profiles for the same user. See screenshot [url removed, login to view]
You have to fix this problem, I don’t know how. In most Facebook Apps, the app will recognize the returning user upon re-installing instead of creating a new user. This is what I need my app to do. No duplicate databases or profiles.
