Webform-civicrm Address fields not being saved in CiviCRM
Are the affected fields selected in the "Fields to lock' dropdown in the "CONTACT FIELD HANDLING" section of the "Existing Contact" field of the webform?

IF so, then see this issue. At the bottom is a link to a much-needed pull request which has been available since Dec 2016. I don't know why it was never merged. With each update of webform_civicrm, I apply the third commit in that PR. Not sure of the importance of the first two commits shown there.
