Update to 4.6 broke CSS

We use a child theme and though the update did not strip the CSS, the highlights are not working. See code

.business:hover {
background-color: #0078c8!important;
color: #fff !important;
}
.business:hover > .meta-heading h3.av-special-heading-tag {
color: #fff !important;
}
.business:hover > .av_font_icon a:before {
color: #fff !important;
}

.visit:hover {
background-color: #c8102e!important;
color: #fff !important;
}
.visit:hover > .meta-heading h3.av-special-heading-tag {
color: #fff !important;
}
.visit:hover > .av_font_icon a:before {
color: #fff !important;
}

.about:hover {
background-color: #003087!important;
color: #fff !important;
}
.about:hover > .meta-heading h3.av-special-heading-tag {
color: #fff !important;
}
.about:hover > .av_font_icon a:before {
color: #fff !important;
}
