css code on a two line entry using the business directory plugin

Hello, on our page http://members.flooringassociation.org/business-directory/308/globalone-supply/ the line for Sales and Mangement Reps is squished together. We added the following css code to the style sheet, but it does not change the line spacing. Can you help? Thanks.

.wpbdp-listing .listing-details .wpbdp-field-sales-reps-and-management {

line-height:20px;
}
