You need to set up your OS so that MIME detection returns something more meaningful for your files.
I thought allow exec() would be a risk?!
So I can remove it from the array.
I suppose the files are corrupt or something inside the files prevent the correct upload, may some filters or entries etc.
As upload succeeded with xlsx files created on my own there is no need for further investigations.
Thank you for quick answering and help, I appreciate your work.
