I think it must be a glitch because it's still calculating BMR for me (I don't wear mine to bed either).
I wonder if this might be an issue with the BMR calculation if one of your profile settings (age, weight, height etc) has been accidentally changed. Worth checking at: https://www.fitbit.com/user/profile/edit
