Hello @samwan i just used your method to edit the checkout page and addresses, but i am getting an error via placing the order that these fields are required even though i dont have these strange letters as fields and i have no idea what they represent:
J is a required field.
B is a required field.
N is a required field.
A is a required field.
S is a required field.
H is a required field.
H is a required field.
check this screen shot
any idea how to solve this ?
