The easiest way that occurs to me is to set the report header to blank after the first header has been printed, ie.

foreach my $report (@reports){
        $givenName = $$report[0] || "";
        $surname = $$report[1] || "";
        $ticket_id = $$report[2] || "";
        $support_id = $$report[3] || "";
        $email = $$report[4] || "";
        write;
        format OUTF_TOP =
.
}
