Blog heading text underlined when changing the font

I’m new to CMS and Webflow which means I don’t necessarily know what all of the elements and objects are called.

I have a Class set up that’s linked to the heading of the blog called “blog heading link.” I’d like to change the font but each time I do it, the text appears to display the link… the text is underlined. How can I change the font with out the text getting underlined? Thank you
