Attribute / Variation not updated on Cart and Checkout page

Seems like after I updated it “Virtual” product once, the product attribute doesn’t append to the product title. Even if I change it back to no virtual, it still show the attribute separately.
It also seems to update the attribute when I change it to virtual product.

However, using this code in functions.php doesn’t seem to update the attribute or product name on the Cart and Checkout page like when I edited with admin.

// Update Virtual Products
function woo_virtual_product($post_id)
{
$children = get_posts(array(
'post_type'      => 'product_variation',
'posts_per_page' => -1,
'post_status'    => 'publish',
));

foreach ($children as $thischild) {
update_post_meta($thischild->ID, '_virtual', 'yes');
}
wp_reset_postdata();
}

add_filter('init', 'woo_virtual_product', 10, 1);

ok. I seem to be able to fix the attribute by doing a bulk edit product category update (even though that category is already added).
However, the attribute name doesn’t append to the product name like before.
