Breath Theme Wordpress Font Change

I go to Breath > General > Choose a Font > then change to the font I want but it doesn't take on the site. I'm not sure if this for the font on the entire site or just in a small spot. I would like to change the font in many different places but am not sure how.

Do I have to change the CSS or html or is there a way to do this on the site?

Thanks!
