How to get rid of fa-angle-down and header menu item in Shapely drop down menu

I’m trying to remove fa-angle down and a header menu item from my php, but can’t seem to find the code which controls it.

I found the following in navwalker.php, but another part of my menu, the menu bars, are in header.php.

if ( ! empty( $item->attr_title ) ) {
            $item_output .= '<a' . $attributes . '><span class="glyphicon ' . esc_attr( $item->attr_title ) . '"></span>&nbsp;';
        } 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 ) ? ' </a><span 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().
}

Is there a part of this code above and here https://github.com/ColorlibHQ/shapely/blob/master/inc/class-wp-bootstrap-navwalker.php, or a part in the code of this https://github.com/ColorlibHQ/shapely/blob/master/header.php that i could remove which would let me go straight from fa-bars, to actual menu, rather than, as now, fa bars->fa-angle down and header menu item->actual menu.

I’ve also asked the theme developers, just trying to find best solution here.

Thanks,
