title: Customizing Checkout Fields and issue translation
body: <p>I'm having problems with WordPress as a multi-site. I have Woocommerce installed on several language sites.</p>
  
  <p>The problem I'm having is, I have a custom language file for Netherlands (NL), which seems to have a translation for 'Apartment' when it comes to checkout. But when it comes to core-fields, the same english text always appears.</p>
  
  <p>Does anyone know what might be wrong with this?</p>
  
  <p>I also noticed that the Postcode field DOESN'T have a placeholder, so it doesn't pickup translation with a checkout field editor. If someone could advise me on how to add this placeholder, that might fix my issue.</p>
