Custom Product Badge in Woocommerce

I am using the following code to add a custom product badge in woocommerce. It adds a free shipping badge on products page. The problem I am facing lately is that for some reason, the free shipping badge disappears after some time. I am not sure if its because of wordpress update or something else. On the product edit page in admin section, I have noticed that checkbox is also unchecked by itself after some time. Could somebody please help?

// 1. Add new checkbox to product edit page (General tab)

add_action( ‘woocommerce_product_options_general_product_data’, ‘bbloomer_add_badge_checkbox_to_products’ );

function bbloomer_add_badge_checkbox_to_products() {
woocommerce_wp_checkbox( array(
‘id’ => ‘custom_badge’,
‘class’ => ”,
‘label’ => ‘Show Custom Badge’
)
);
}

// —————————————–
// 2. Save checkbox via custom field

add_action( ‘save_post’, ‘bbloomer_save_badge_checkbox_to_post_meta’ );

function bbloomer_save_badge_checkbox_to_post_meta( $product_id ) {
if ( defined( ‘DOING_AUTOSAVE’ ) && DOING_AUTOSAVE )
return;
if ( isset( $_POST[‘custom_badge’] ) ) {
update_post_meta( $product_id, ‘custom_badge’, $_POST[‘custom_badge’] );
} else delete_post_meta( $product_id, ‘custom_badge’ );
}
