How to get rid of bullet points in ...

In the login area of my membership site, on the permalink /mitglieder , I displayed a grid of products, using the plugin "essential grid". Now my Theme seems to add bulletpoints to each product.... ( http://screencast.com/t/jdRujWfn6t )

I want to get rid of those bullet points, but I was not able to find the CSS. Could somebody help me? (I granted access since you have to login to see the site) . That would be great!
