css bulleted list issue on shortcode

I’m using shortcode in a table view to show the speakers with extra information for the sermons of our church. It’s working great only I have an issue with the view, before every date a bullet appear, i tried to remove it with

ul {
list-style-type: none;
}

but this don’t solve the problem.
