How to remove top menu item and font awesome icon in WordPress menu?

In my WordPress menu I have a top or header menu item. I know how to find it and use CSS to hide it, but that's not exactly what I want.

At the moment I have menu bars which, when pressed, go to fa-angle-down and header menu item, which, when pressed, go to the actual menu. I'd like to remove this intermittent menu stage consisting of header menu item and fa-angle-down so that the user is taken straight from bars to actual menu. I've looked in my header.php and found fa-bars, but nothing to indicate its attribute, and in navwalker.php, where I found fa-angle-down, but nothing to indicate how it's connected to fa-bars.

I'm assuming that I just have to remove a certain part of navwalker.php, but which part?

Here is my navwalker.php: https://github.com/ColorlibHQ/shapely/blob/master/inc/class-wp-bootstrap-navwalker.php

Here is my header.php: https://github.com/ColorlibHQ/shapely/blob/master/header.php

Here is php which i think controls it.

$item_output = $args-before;

        /*
         * Glyphicons
         * ===========
         * Since the the menu item is NOT a Divider or Header we check the see
         * if there is a value in the attr_title property. If the attr_title
         * property is NOT null we apply it as the class name for the glyphicon.
         */
        if ( ! empty( $item-attr_title ) ) {
            $item_output .= 'a' . $attributes . 'span class="glyphicon ' . esc_attr( $item-attr_title ) . '"/spannbsp;';
        } else {
            $item_output .= 'a' . $attributes . '';
        }

        $item_output .= $args-link_before . apply_filters( 'the_title', $item-title, $item-ID ) . $args-link_after;
        $item_output .= ( $args-has_children ) ? ' /aspan class="dropdown-toggle shapely-dropdown" data-toggle="dropdown"i class="fa fa-angle-down" aria-hidden="true"/i/span' : '/a';
        $item_output .= $args-after;

        $output .= apply_filters( 'walker_nav_menu_start_el', $item_output, $item, $depth, $args );
    }// End if().
}

Here is html:

                        i class="fa fa-bars"/i
                    /div

                    div class="module-group right"    
                        div class="module left"


                            div class="collapse navbar-collapse navbar-ex1-collapse"ul id="menu" class="menu"li id="menu-item-3530" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-has-children menu-item-3530 dropdown"a title="Contact" href="https://4309.co.uk/contact/"Contact /aspan class="dropdown-toggle shapely-dropdown" data-toggle="dropdown"i class="fa fa-angle-down" aria-hidden="true"/i/span
