Remove icon from child-menu headers

There is a strange icon above my child menu headings. I have nothing entered in the Font Awesome area on any of the menu items.

Here is a link to the site. Hover over Services and you'll see the icon above or next to the 4 column headers

Not sure if this is the correct way to do it, but I added the css below to the custom css section under the Advanced tab. It seems to have worked.

a.group::before, a.users::before {content: "";}
