You can see who your teammates had in their wk 3 games by clicking their team name in the league table of your group david. Have a look, then look at their wk 2 team, it could be that they attempted to make changes but didn't confirm properly? In which case they wouldn't even have the back-up of using last week's team. Of course there is the possibility that the team actually was saved but scored zero points david. Stranger things have happened.
