Feed Them Social plugin causing bullets in sidebar

Once installed, the Feed Them Social plugin forces unwanted bullets to appear in sidebar widgets on a site I am building, as shown here: http://mamayogachannel.com/wp-content/uploads/2015/04/Bullets-in-sidebar-Widgets.png

I really like the Feed Them Social plugin and have installed in for countless clients, but this time, I can’t figure out what needs to change in the css to prevent the unwanted bulleted list from occurring whenever I install the plugin.

Before the plugin is installed, the widget icons look normal, as shown here: http://mamayogachannel.com/wp-content/uploads/2015/04/4-8-2015-12-56-02-AM.png

How can I remove the bullets and keep the Feed Them Social plugin?
