HELP! Incorrect Current Weight - Is it Possible to Change it?

When I first got the app I weighed myself with clothes on really quickly and inputed the number just to see how you set up the app, the next day I weighed myself properly and changed the current weight to begin using the app. But the app congratulated me saying I've lost 7lb. Is there anyway to change the current weight without it thinking you have lost weight?? I would like to change the pounds lost number from 10 to 4 as I have actually only lost 4lb.

thanks!
