I have a lead that had complete contact information in their profile. However, when I imported a list of webinar attendees from a partner company that included this lead, their phone number and address where changed to null. How is this possible? I was under the impression that list import only changed fields that are populated with different information and that empty fields do not owerwrite populated fields. Is this not true?
