I'm trying to add a new field to the mapping of the contact_originating_lead relationship (to pass the contents of a custom field from the lead to the contact when the contact is created from qualifying a lead). It lets me click New, and then select my custom field as the source and as the destination, and then click OK. I get no errors, but it does not add the mapping. I've tried this with three different custom fields and no go. Two of the fields are lookups, and the third one is just text (same length for both).
Am I missing a step, or is something just broken?
