Start by reproducing the supplied vCard import in the Contacts app, then inspect ContactDetails.vue and addressbooks.js for handling of ITEM3.ORG and ITEM4.TITLE. Check contact.js for the parsed vCard data and confirm that the company and title are both displayed, editable, and preserved after export.
