Font styles

My client has bought the plugin and dislike the red italic font that comes up when I use the following:

[rem_list_properties top_bar=”enable” style=”3″ class=”col-sm-4″ masonry=”enable”]

How can one chnage the font for listing, search for sale and search for rentals as all these instances show the font in italic and red and we would like it black and Helvetica.
