Can't remove list bullet from widget

Thanks for a great plugin. I am trying to use it in the sidebar of my site and it’s displaying a disc list bullet before each item. See page http://www.travelnasia.com/category/food-drink/

Also, the widget is supposed to be displaying 10 random posts, but seems to be displaying the 10 most recent posts instead. Here’s a link to a screenshot of the settings. I am using the default CSS.
