Encountered this using PHP 7.4.19 both inside a docker container and 7.3 (don't have more
specific info) on the Pantheon hosting platform. 

Confirmed that the mime type returned by

    $finfo     = finfo_open( FILEINFO_MIME_TYPE );
    $real_mime = finfo_file( $finfo, $file );

is
application/vnd.openxmlformats-officedocument.wordprocessingml.documentapplication/vnd.openxmlformats-officedocument.wordprocessingml.document
for a docx file that was exported from Google Drive. 

This problem did not occur with a docx file created in LibreOffice.

We encountered this problem on php 7.3.11, on FreeBSD 12.0, with some XLSX and DOCX files.
Is there an update or a workaround ? Or a scheduled patch maybe ?

I experience this issue with PHP 7.4.6 on Ubuntu 20 using docx format. I've tried opening and
saving it from office365 but that did not solve it.

Similar to what ryanmcquerry reported, if you open and save your xslx file in Excel, it also solves
the problem. That's a good enough workaround for the time being, while the bug is not fixed.

I am seeing this duplication with docx files downloaded from Google Docs.  When I open them in Word
and do a "Save As", it works again.
