Theme can not change the way Meta is shown in order review & Cart

as per the implementation in your plugin you added a meta “rn_entry” to item

as we want to customize the way the theme show the added option ,

the generic way is to use WooCommerce Core Function wp_parse_args() which require the meta array in specif format you introduce a new Array

now the problem is on order review page you used filter “woocommerce_order_item_meta_start” to print data to order , can you please change that, so that we don’t need to touch the plugin core , to achieve the UI Edit via the woocommerce/order/order-details-item
