Recent Tweets not appearing in sidebar

Hi, I installed and tweaked the widget, and have successfully filled out the authentication fields. The five tweets that were already on my Twitter feed appear on my blog’s sidebar, but the tweets I’ve published since (in the few minutes immediately after configuring the widget) do not. Could you assist?

The site I’m working on is:
