title: Custom Birth Date field not showing in my account edit details page
body: <p>I would like to add a birth date field to both checkout and my account edit details page. I followed the suggested code over at this thread <a href="https://stackoverflow.com/questions/39428150/add-a-custom-field-to-checkout-and-to-my-account-user-details-on-registration">here</a> and managed to get the custom field on checkout and admin edit user but the birthdate field is just not appearing on my account edit details. What could be wrong?</p>
