Hello Paul,

I am sorry for the late reply.
I cannot replicate this issue on my local. Here my screenshot: http://screencast.com/t/ZCvFlkzS and http://screencast.com/t/vT12d41Poj8 . I suspected that there is cache on your browser which caching the number of tweets. Can you try refresh or clean your browser cache and see if this issue is still persist?

Hope this will help.
Thanks.
