System Check > File Integrity > piwik-archive.log (never deletes)

Hi,
I have installed Piwik all ok, but in system check the file integrity always reports to delete “piwik-archive.log”.
Even when I delete this, the next day the file re-generates and the system tells me to delete it. So the cycle repeats.

Did something go wrong during install?
Can you anyone help advise?
Thanks.
