[Plugin: WordPress SEO by Yoast] Generating good looking titles for pages

For our site, the title appears like this https://dl.dropbox.com/u/14057353/awareness%20institute%20on%20google.png

In the snippet for this plugin, it says the main page will look like this:
Welcome – Awareness Institute

What’s going on?

thanks,
Andrew
