PHPSpreadsheet generates empty file if it containts more than 16 rows - php

Question

I am generating a xlsx file with PHPspreadshet and it always gives me an empty file (0kb) when it has more than 16 rows. I already tried to search for erros etc. and found nothing. It just depends on the row.
The Spreadsheet (Html for testing):
And when I switch following lines:
$this->sheet->setCellValue("A16", "Besetzt");
To
$this->sheet->setCellValue("A17", "Besetzt");
The generator (execute() is the entry point):
class ExcelOperation extends AbstractOperation
{
private function addWork($cell, $name = "", $phone = ""){
if($cell != null){
$richText = new \PhpOffice\PhpSpreadsheet\RichText\RichText();
$boldText = $richText->createText($name);
//$boldText->getFont()->setBold(true);
$richText->createText("\n".$phone);
$this->sheet->getCell($cell)->setValue($richText);
$this->sheet->getStyle($cell)->getAlignment()->setWrapText(true);
$this->sheet->getStyle($cell)->getAlignment()->setHorizontal(\PhpOffice\PhpSpreadsheet\Style\Alignment::HORIZONTAL_CENTER);
}
}
