Hey John,
Can you try this instead? You’ll need to add the class hovered-set to each column. Add the code below to the JS Code section in the customizer.
(function ($) {
$(function() {
$( '.hovered-set' ).each(function() {
$(this).find('i,h6').hover(function() {
$(this).parents('.hovered-set').addClass('hovered');
}, function() {
$(this).parents('.hovered-set').removeClass('hovered');
})
})
})
})(jQuery)
You’ll need to add this code to the CSS Code section as well.
.hovered-set.hovered i:before,
.hovered-set.hovered h6 {
color: blue;
}
Let us know how it goes! 
Ben
