In shopify checkout form 'shipping address', the state fields options value captured as code instead of state name, my shopify store display all customer addresses state in code thats include displaying in EDM,  Customer Listing Page.. and etc.
ex:
State: 'Selangor' become '10'
State: 'Kuala Lumpur' become '14'
