Power Rankings

Does anyone know why on the PS3, the power rankings put your team near last place when playing manually (not using sim)?

I'm 25-0, and my team is 23rd on the power rankings.

If I use sim games, this never happens, only when I manually play every game.

Could be a bug. I must admit I never pay much attention to the power rankings and in past games that have used the PDA I've usually disabled or ignored the power ranking emails.
