How to disable auto create customer profile after edit order?
This is happening because the inline customer profile form has the country selected, which is all that's required for a field value to be present. I believe we should add a fix to Drupal Commerce core to prevent this, but I don't know off the top of my head if there's already an issue in the queue for it. Feel free to search at https://www.drupal.org/project/issues/commerce and file an issue if you don't see it already. Thanks!
