Unwanted changes made while trying to edit a docx file.

[mayankitt]

I wrote some code to edit documents through phpWord. But the changes didn't take effect and there were some unwanted changes. When I tried to simply load the file into the buffer and save it to the disk without making any changes to the document, the changes still persisted.
The code I used:

$source = "demoFile.docx";
$phpWordObj = \PhpOffice\PhpWord\IOFactory::load($source);

$objWriter = \PhpOffice\PhpWord\IOFactory::createWriter($phpWordObj, 'Word2007');
$objWriter->save('demoFileUpdate.docx');

The screenshots of the original and updated files are given below:

Hope to resolve this at the earliest.
