First of all, the list of recently earned points/bucks is not the same when viewed in the app versus on the web. As one example, I got my 50 lifetime points for using the app for the first time. They show up in the app on 1/3 but they do not show up when I view my statement through the website at all.
Second, the Fitbit data from January 2 is wrong. It is showing 13 points but I have over 14,000 steps for that day. Several syncs have been performed since then and my Fitbit data for January 3 and January 4 is correct. I can provide a screen shot from my Fitbit dashboard confirming the step data if need be.
