Change Title CSS

I have an issue with the way the Titles display. I know it is because of the Theme I am using. It puts two lines behind anything using the Title identifier (which I like for the rest of the site) but on my RSS Feeds page every Title has the lines not only behind the name but running through it as well. Can I edit one of the files within the plugin so as to eliminate this?
