what is wrong with my ticker (NOT my heart!)

Hummmingbird

Ok so i have gone from 160lbs-158 and yet my ticker is not reflecting this. People have told me to go into settings and to update that portion of my profile. I did that a couple weeks ago and made my current weight 160.
today i checked-in (at the tope of the my home tool bar) and put my new weight in, but nothing showed on my ticker! I have lost almost 2 lbs so what is going on?! help!
