Do you see it go from 0 to 400 calories or are you saying it has 400 calories when you look at it first thing in the morning?
If it's the second then this is probably OK.
As well as tracking calories you burn through activity, your fitbit also tracks your BMR calories. These are the calories you burn just keeping your body alive (even when asleep). They are calculated from your profile settings (age, weight etc) so you needn't be wearing your fitbit to get them. What you are seeing is the total BMR calories since midnight.
