Repared file

[QuentinPi]

Hi everyone,
I have a problem when I open the generated document. LibreOffice displays a message about "repairing the file as the file may be corrupted" (which works). Is there a way to remove this message ?
Thank you for your help.

I'm also interested in this.
It might be that the compression of ZipArchive is the problem here.
