доброй утро ув форумчане!

не могу нормально выгрузить данные.
выгружаю следующим образом:

$bill_id = $_GET['bill_id'];
    $num = $_GET['num'];
    $date = $_GET['date'];
    $name = $_GET['name'];
 
        $csv_output = '';
            
    $csv_output .= "\n";
    $csv_output .= '"Накладная №";"'.$num.'";';
    $csv_output .= "\n";
    $csv_output .= '"Дата";"'.$date.'";';
    $csv_output .= "\n";
    $csv_output .= '"ФИО заполняющего";"'.$name.'";';
    $csv_output .= "\n";
    $csv_output .= "\n";
    $csv_output .= "\n";
    
            $total_priceP_value = 0;
            $total_priceR_value = 0;
            $pp = 1;
            $a1_query = mysql_query("

            while ($a1_values = mysql_fetch_row($a1_query)) {

                        $csv_output .= '"'.$a1_values[9].'";';

                        $pp++;
                        $total_priceP_value = $total_priceP_value + $a1_values[8];
                        $total_priceR_value = $total_priceR_value + $a1_values[9];

            $csv_output .= '"";"";"";"";"";"Сумма";"'.$total_priceP_value.'";"'.$total_priceR_value.'";';
            
    // Output to browser with appropriate mime type, you choose ;)
        header("Content-type: text/x-csv");
        header("Content-type: text/csv");
        header("Content-type: application/csv");
    header('Content-Type: text/xml, charset=UTF-8; encoding=UTF-8');
        header("Content-Disposition: attachment; filename=search_results.csv");
        echo $csv_output;
        exit;

в итоге получаю в файле следующее
