[SOLVED] Add class="no_icon" to menu link

I'm using a WP plugin called External Links which places a little arrow icon next to external links.

You can override individual links with: class="no_icon"

I have one link in the primary horizontal menu bar that is external. I can't for the life of me find where to properly add the class="no_icon" to get rid of the little arrow icon on this one link.

I searched the forum and found a couple similar posts but nothing worked including modifying bfa_header_config.php.

I also tried adding <class="no_icon"> to the HTML inserts.

As you can see, I have no idea what I am doing.

Is anybody familiar with this plugin and has an idea how to modify a menu link to remove the arrow icon?
