Is there a bug with sending too many log activity posts to quick?

[JaredD]

I have made an app on my website in which I can update my steps for the month. It is only possible to update one day at a time, So I used a for loop to go through the days that are updated and send the log activity post for that day to fitbit. The problem I am having is I am getting responses from fitbit for everyday but fitbit did not update each day. It usually will only update one day. Do I need to put some time between each log activity post?

Specifically, what are the requests that you're making?

Here is the responses that I am getting from FitBit...

but as you can see only Nov 29th stats actually updated in Fitbit. I then try again with a new log activity request at a different time and it returns me a response of (old request steps + new request steps). So fitbit is receiving these requests but not displaying for some reason until I create another request for the same day and then it adds all together.
