h1 header creating unwanted capital letter

Hello. My my site is located at: http://www.houseostone.com

I am using GP premium and my problem is that when I am using the page header feature and create an H1 heading I get an unwanted capital letter...in this case a capital O

I want my heading on the homepage to be House of Stone...NOT...House Of Stone. In other words I need to get rid of the capital O in the second example. Even though it is a lower case O in the page header module it still shows as a capital on the page. An H2 heading does not show this behavior. I have cleared the cache but don't know what else to try.

Thanks for you help.
