Strange Excessive Food totals

On several days a week when I complete the Food Diary I get strange excessive amounts of expected calories.
For yesterday it reported that I need to eat 30,250 calories. Thus, since I ate only 1345 calories in five weeks I will weight a negative 240 pounds.
I happens on various day but always at least once a week for the last two months.
Where are these fictitious numbers coming from?
TIA
