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.

I got the same issue with finfo(FILEINFO_MIME_TYPE, $file) in php 7.4.5 on linux

This also is affecting word documents.

Tested with:
- MAC OS 10.15.4/ PHP 7.3.4
- Ubuntu 16.04.6 LTS / PHP 7.3.13
- Ubuntu 16.04.6 LTS / PHP 7.3.14


$ file --mime-type test.docx
test.docx: application/vnd.openxmlformats-officedocument.wordprocessingml.document
$ php -a
Interactive shell

php > print mime_content_type('./test.docx');
application/vnd.openxmlformats-officedocument.wordprocessingml.documentapplication/vnd.openxmlformats-officedocument.wordprocessingml.document
