We exported our latest game and stats/results to two of our previous games were merged and results changed. Our player stats now include other teams players from the tournament game.

Exporting would not change the stats in iScore. It just sends your data to the iScore server. When you view Team Stats in iScore, it will show all the players that are on that team's roster. You should go to Team Manager, select your team, and select Roster, and make sure only the players from your team are listed there.
