Menus won't link to category on mobile site

Hello, I am having an issue I can;t resolve as yet. Am running the FlyingNews theme.

I have set up my menus correctly, and everything seems good except when I visit our site on my cell phone, the drop-down menu does not link to the categories it’s supposed to.

The menu shows the options, and when I select my option it simply stays on the same page, showing my selection in the menu box.

I can;t find any settings for this, and have combed the back-end from head to toe.

My coding looks like this for the Header menu which is having issues, can anyone tell me what’s wrong?

<?php if (jwOpt::get_option('menu_type', 'menu-1') == 'menu-1') { ?>
                            <nav class="top-bar top-bar-jw" role="navigation">
                                <section>
                                    <?php
                                    $a = wp_nav_menu(array(
                                        'theme_location' => 'primary_navigation',
                                        'container' => 'false',
                                        'menu_class' => 'top-nav',
                                        'menu_id' => 'jw',

                                        'link_after' => '',
