Custom post type not appearing in WordPress admin menu

I am facing an issue. I’m new in wordpress. I created a function for custom post types. This is my code.

function my_cpt(){
    $labels = array(
        'name' => 'SM & Points Templates',
        'add_new' => 'Add New SM & Points Template(s)',
        'add_new_item' => 'Add New SM & Points Template(s)',
        'edit_item' => 'Edit SM & Points Template(s)'
    );
    $args = array(
        'labels' => $labels,
        'menu_icon' => 'dashicons-arrow-right-alt',
        'public' => true,
        'supports' => array('title')
    );
    register_post_type('custom_settings', $args);
    $labels1 = array(
        'name' => 'Fine Print',
        'add_new' => 'Add New Fine Print',
        'add_new_item' => 'Add New Fine Print',
        'edit_item' => 'Edit Fine Print'
    );
    $args1 = array(
        'labels' => $labels1,
        'menu_icon' => 'dashicons-arrow-right-alt',
        'public' => true,
        'supports' => array('title')
    );
    register_post_type('fine_prints', $args1);
    $labels2 = array(
        'name' => 'Post Hints',
        'add_new' => 'Add New Post Hint',
        'add_new_item' => 'Add New Post Hint',
        'edit_item' => 'Edit Post Hint'
    );
    $args2 = array(
        'labels' => $labels2,
        'menu_icon' => 'dashicons-arrow-right-alt',
        'public' => true,
        'supports' => array('editor')
    );
    register_post_type('post_hints', $args2);
    $labels3 = array(
        'name' => 'States',
        'add_new' => 'Add New State',
        'add_new_item' => 'Add New State',
        'edit_item' => 'Edit State'
    );
    $args3 = array(
        'labels' => $labels3,
        'menu_icon' => 'dashicons-arrow-right-alt',
        'public' => true,
        'supports' => array('title')
    );
    register_post_type('states', $args3);
    $labels4 = array(
        'name' => 'Help',
        'add_new' => 'Add Help',
        'add_new_item' => 'Add Help',
        'edit_item' => 'Edit Help'
    );
    $args4 = array(
        'labels' => $labels4,
        'menu_icon' => 'dashicons-arrow-right-alt',
        'public' => true,
        'supports' => array('title')
    );
    register_post_type('helps', $args4);
}

add_action('init',  'my_cpt');

The issue is that First 4 posts are appearing in admin menu. But last Helps is not appearing in menu bar. Where am I wrong? Please see the this image.

After States, there should be Help.

EDIT:

When I was adding the last custom post, I made a small mistake. I added this code.

$labels4 = array(
    'name' => 'Help',
    'add_new' => 'Add Help',
    'add_new_item' => 'Add Help',
    'edit_item' => 'Edit Help'
);
$args4 = array(
    'labels' => $labels4,
    'menu_icon' => 'dashicons-arrow-right-alt',
    'public' => true,
    'supports' => array('title')
);
register_post_type('states', $args4);

Now the last two custom post types had same id states. But when I saw it, I changed it to helps. It was appearing when I added it for the first time with states id. But when I changed it to helps, It disappeared. In the top menu, Helps is visible under New but not in admin menu.
