insertNewRowBefore using phpspreadsheet not change coordinate of cell name

I have excel file 3 rows. I give name,amount1 for first row first column. Third row is =amount1+A2.

200  ~ amount1
300
---
500
---

Now, I want to insert one row before row 1 and setValue to column 1. I have using phpspreadsheet to do this. The name, amount1 not go together with value 200 to next row. This affect the formulae result.

new row  ~ amount1
200
300

error

The code as below:

require '../vendor/autoload.php';
use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\Writer\Xlsx;
use PhpOffice\PhpSpreadsheet\Cell\Coordinate;
$reader         =\PhpOffice\PhpSpreadsheet\IOFactory::createReader("Xlsx");
$spreadsheet    =$reader->load("File1.xlsx");
$sheet          =$spreadsheet->getActiveSheet();
$sheet->insertNewRowBefore(1);
$sheet->setCellValue('A1', 'new row');
$writer = new Xlsx($spreadsheet);
$writer->save('File1_output.xlsx');

From getNamedRanges(), update $range->setValue('Sheet1!$C$2');

Sheet1!$C$1->Sheet1!$C$2

require '../vendor/autoload.php';
use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\Writer\Xlsx;
use PhpOffice\PhpSpreadsheet\Cell\Coordinate;
$reader         =\PhpOffice\PhpSpreadsheet\IOFactory::createReader("Xlsx");
$spreadsheet    =$reader->load("File1.xlsx");
$sheet          =$spreadsheet->getActiveSheet();
$sheet->insertNewRowBefore(1);
$sheet->setCellValue('A1', 'new row');
 foreach ($spreadsheet->getNamedRanges() as $range) {
  if($range->getName()=='amount1'){
    $range->setValue('Sheet1!$C$2');
   }

  }
$writer = new Xlsx($spreadsheet);
$writer->save('File1_output.xlsx');
