I've noticed upon matching mapping fields in the import process that for some fields in the file they are missing in the CiviCRM drop-downs. For instance, for a field named "Home County' the CiviCRM drop-down for 'County does not appear. But choose 'Employee of' and 'County' appears. In fact, it is one of the only other, unrelated fields that it appears.
Please advise. Thank you in advance.
