Mine did the same thing. Go to where you input your weight and click on edit old entries delete all your old weights that are less then what you weigh now that's how you fix that

For those users who may not want to delete historical data, you do not have to. Just enter a date/weight at least one day older than your oldest date/weight. The calculations are solely based on the oldest date/weight.

Alternately, navigate to MY HOME > Check-in > Edit Previous Entries.
a. Enter a new value in the Starting Weight text box and click Change; or
b. Scroll down and click on the highest page number to take you to the oldest date/weight entry. Once you find your oldest date/weight entry, under Add New Entry, enter the new date/weight and click Add New Entry. That will replace the oldest date/weight with your new one.
c. If you want to keep all of your historical data, Add New Entry at least one day older than the oldest date/weight.
