Duplicate folders ver. 2.9

[AchLive]

Hello everyone, just to point out that with the installation of version 2.9 the following folders are duplicated:
/includes/libs/PhpSpreadsheet-master/vendor/markbaker/matrix/classes/src/Functions
/includes/libs/PhpSpreadsheet-master/vendor/markbaker/matrix/classes/src/Operations
by variation of the initial capital letter in version 2.9 while it was lowercase in the previous version.
Thanks for the support

Nothing critical with this. You can remove includes/libs/PhpSpreadsheet-master and copy includes/libs/PhpSpreadsheet-master from 2.9 archive.
