Notification widget keeps moving to bottom of list

I'm running iOS 5.0.1 and have the notification widgets set to sort manually instead of by time.

Any time I move the Stocks widget to any location other than the bottom it looks fine until I leave the Notifications setting page. If I back out to the main Settings screen and return to Notifications the Stock widget has moved back to the bottom.

Has anyone else seen this? Is there a setting somewhere that I can reset? Or is this a bug I should submit?

Thanks.
