Change the start date on the weight report and it should show correctly. Since you only have one weigh-in, it helps to go back a little more in the start date on the report. For example, I changed it to 1/11/14 and I now see the blue line value of your latest weigh-in. Once you get more weigh-in's recorded, you shouldn't have to change that start date unless you want to.
Hope that helps,
