I am using in my Wordpress 2 plugins woocommerce and Print Address Labels that as the name says it prints the labels of the requests, however I have a problem, after the last update of woocommerce database simply stopped appearing the type of freight that the customer chose, which is marked by the [shipping_method] option in the plugin.
Where was it to appear "Fixed rate" is showing " a:1:{i:0;s:11:"flat_rate:1";} ".
Basically from what I understand, the plugin is not picking up the Freight name which in the case would be "Fixed Rate" it is printing on screen the SQL field that is saved.
As can be seen in the following example in the wp_postmeta table.
I searched the woocommerce documents and found nothing related to this problem, and I would like to know if anyone can help me because we have several types of delivery and need to appear on the label.
