Columns touching after update

Hi there,

I recently updated my WordPress to 4.5.2, and my columns are now touching. They don’t quite overlap, but it looks messier than when there was more separation. http://www.swppa.org/agefriendly/

I added this CSS to Highend Options > General Settings > Custom CSS, per another forum topic, but nothing has changed:

.vc_col-lg-1, .vc_col-lg-10, .vc_col-lg-11, .vc_col-lg-12, .vc_col-lg-2, .vc_col-lg-3, .vc_col-lg-4, .vc_col-lg-5, .vc_col-lg-6, .vc_col-lg-7, .vc_col-lg-8, .vc_col-lg-9, .vc_col-md-1, .vc_col-md-10, .vc_col-md-11, .vc_col-md-12, .vc_col-md-2, .vc_col-md-3, .vc_col-md-4, .vc_col-md-5, .vc_col-md-6, .vc_col-md-7, .vc_col-md-8, .vc_col-md-9, .vc_col-sm-1, .vc_col-sm-10, .vc_col-sm-11, .vc_col-sm-12, .vc_col-sm-2, .vc_col-sm-3, .vc_col-sm-4, .vc_col-sm-5, .vc_col-sm-6, .vc_col-sm-7, .vc_col-sm-8, .vc_col-sm-9, .vc_col-xs-1, .vc_col-xs-10, .vc_col-xs-11, .vc_col-xs-12, .vc_col-xs-2, .vc_col-xs-3, .vc_col-xs-4, .vc_col-xs-5, .vc_col-xs-6, .vc_col-xs-7, .vc_col-xs-8, .vc_col-xs-9 {
padding-left: 15px !important;
padding-right: 15px !important;
}
