Bullet point showing

I searched the forum and someone had posted this as their solution to removing the bullet point image that appears before each social icon:

.widget .zoom-social-icons-list li {
content: none;
padding: 0;
}

I placed this in the “Customize/Additional CSS” section of the website and saved it, but I’m still seeing the bullet images. Any thoughts? Link to website below. Just scroll down all the way to the footer to see the icons:
