Page appears after de registering from menu

This is controlled by the wp_nav_menu argument fallback_cb, which is the wp_page_menu function by default. Set it to false to show nothing in the case a menu isn’t assigned.

wp_nav_menu( array(
    'theme_location' => 'footer-menu',
    'menu_class'     => 'footer-links-menu',
    'fallback_cb'    => false,
) );
