Try changing float: left; to display: inline-block; around line 2059 –

.genesis-nav-menu .menu-item {
    float: left;
    list-style-type: none;
    margin: 0;
    padding: 0;
    text-align: left;
}

.genesis-nav-menu .menu-item {
    display: inline-block;
    list-style-type: none;
    margin: 0;
    padding: 0;
    text-align: left;
}
