title span freaks out on second word

I have a span on Page titles to alter how its displayed in the navigation. For the actual Page h1, I take out the effects of the span.
On pages where the span is on the first word < span>partner</span > agencies, all is cool. But when the span is on the second word our < span>clients</span > the h1 gets very strange and knocks the word out of the div.
The html and css validate, and the pages use the same template.
You can see the site here:

Click on any of the nav links and look at the text in the blue bar on the right.
Thanks!
