blog title link problem

When creating a blog post, the url that is generated has a space after the category and causing an error when linking.

List of posts: http://www.capturevascular.com/news

When you click the link the link on the page does not have a space and gives a 404 error: http://www.capturevascular.com/news/jack-springer-appointed-as-executive-chairman-of-capture-vascular/

This is not apparent when testing the page from the blog posting itself: http://www.capturevascular.com/news%20/jack-springer-appointed-as-executive-chairman-of-capture-vascular/

The space is adjusted with the %20 and works. Andy help removing the space would be appreciated as I cannot see where it is in the category or any other section I’ve looked to remove it.
