Reply To: Primary Navigation items appear in reverse order

On line 2274 you have float: right; which makes the menu items show up in reverse. You can change it back to float: left; and it will show up back to normal –

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

Change this to –

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