White bullet after updating

Hello, since updating to the latest version of this plug-in I noticed a white bullet that strikes through the beginning of the text in each testimonial. I’m not sure how to remove it so maybe you can guide me in the right direction. You can see the issue at: http://www.advancecncmachining.com all the way at the bottom right hand corner of the page. Thank you for your help.
