custom fields in Quick/Bulk Order Form not displaying

Hello,

i am using the latest version of WooCommerce Quick/Bulk Order Form where i’ve added 2 custom fields (packaging type + quantity in package) to be displayed for variations/single products.

The issue i am facing is that on my localhost, the values are returned ok for both single products and variations, but online only the single products return the values. For the varitions those are empty, although by check my database those custom fields are assigned for the specific variation.

elseif ( 'product_variation' == $post_type ) {
                    $product = new WC_Product_Variation($prod);
                    $parent = get_product($prod);
                    $id = $product->variation_id;
                    $price_html = $product->get_price_html();
	                if(preg_match('/<ins>(.*?)<\/ins>/', $price_html)){
					    preg_match('/<ins>(.*?)<\/ins>/', $price_html, $matches);
					    $price_html = $matches[1];
					}
					$price_html = strip_tags($price_html);
					$price = $price_html;

					/* custom option to display our packaging type on the frontend via json*/

                    $cs_size_pack_var = get_post_meta($id, '_cs_size_pack_var', true);
                    $cs_select_pack_var = get_post_meta($id, '_cs_select_pack_var', true);

                    $wcbulkorderpacktype = $cs_size_pack_var . ' - ' . $cs_select_pack_var;

the id of the variation is returned correctly im guessing that it might be a issue related to the get_post_meta?!?

Thank you, any help is kindly appreciated!
