case activity, send a copy - empty row

when editing a case activity, expand the "send a copy" panel –
there is an empty row

this is because the array element for the client's record is a subset array – it's one level deeper than the rest of the relationship records, and so the necessary values are not passed to the template.

see: CRM/Case/Form/Activity.php
around 294

$this->_relatedContacts needs to be fixed so that all elements are structured the same.
