Next, go to  your registration form, click on edit, then click the underline blue text which says “Automatically set profile question data for users who sign up or update using this form”.

Look for "Auto answer this question under database origin", then tick the box for "Auto answer this question", "New answer don't remove old data" and also tick the box for the specific origin you want your customers to be flagged under.
