Does the exercise area have a default?

Smorrison68

For the past 3 days, I keep seeing 86 listed under exercise in the Area listed with my daily count of calories. In the morning, right after I list what I'm having for breakfast the exercise number pops up and I have not listed exercise for the day but again today the number 86 is listed right after daily calories + food + exercise + calories left? Is this a default? I don't wanna eat extra calories I don't actually have becuz it will affect how fast I lose weight. Later in te day when I exercise those numbers are added with the 86 and not sure what's up with this? Help!
