PhPWord not adding footnote numbers

[asianindexing]

I am using the following code to convert and docx file to html

$objReader = WordIOFactory::createReader('Word2007');
$phpWord = $objReader->load('test.docx');
$section = $phpWord->addSection();
$objWriter = \PhpOffice\PhpWord\IOFactory::createWriter($phpWord, 'HTML');
$objWriter->save('helloWorld.html');

PhpWord is not adding clickable number to footnotes while converting a file to html. Please see the following image.

However, in text clickable numbers are showing fine in text. Pelase see the following image.
