title: Google Enhanced Ecommerce, set_checkout_option
body: <p>I integrated Google Enhanced Ecommerce on a project and integrated calls for the various checkout steps (billing address, shipping address, shipping method and payment method). I'm correctly sending the 'set_checkout_option' event and I set the steps for GA administration, but I still see the steps not populated. Has anyone been in the same situation?</p>
  
  <p>PS: Billing address I think it is always populated because of course it is step 1 and it takes it automatically with the 'begin_checkout' event.</p>
