Navigation bar isn't unhighlighting

Hi,

So the plugin is working perfectly apart from one small issue. When I click something on the nav bar, it highlights the selected page but it also doesn’t unhighlight the previous page. If I click through every page then they will all end up highlighted.

I have this code under ‘Click Code’

// highlight the current menu item
jQuery('ul.menu li').each(function() {
	jQuery(this).removeClass('current-menu-item');
});
jQuery(thiss).parents('li').addClass('current-menu-item');

jQuery(document).ready(function($) {
    var navigation;

    navigation = $('#primary-navigation');

    navigation.find('a').click(function() {
        navigation.removeClass('toggled-on');
    });
});

I’m using the standard twenty fourteen theme. Can anyone help?

I have also tried

// highlight the current menu item
jQuery('ul.menu li').each(function() {
	jQuery(this).removeClass('current-menu-item');
        jQuery(this).removeClass('current_page_item');
});
jQuery(thiss).parents('li').addClass('current_page_item');
jQuery(thiss).parents('li').addClass('current-menu-item');
