PHPExcel does not set the papersize correct in excel 2007

Question

SOLVED
(Solution explained under the question)

I am trying to change the page setup for a XLSX file with PHPExcel.
But whenever i change the papersize, it results in a USER defined size with the wrong width and height.

This is what i do:

$sheet->getPageSetup()->setPaperSize(PHPExcel_Worksheet_PageSetup::PAPERSIZE_A3);
$sheet->getPageSetup()->setOrientation(PHPExcel_Worksheet_PageSetup::ORIENTATION_LANDSCAPE);

In the XLS file, it works correct.
But in the XLSX file not.

I already searched on google and on the forum but i could not find anything about it.
Am i doing something wrong?

I am testing in Libre Office (i also checked it on excel but it has the same problem)

The result of a XLSX file:

Let me know if you need more information.

Thanks in advance!
