Kiwi Syslog server - Archive task does not run on a schedule

I am running Kiwi Syslog server 9.4.1 and I have created an archive task to copy all messages to a file share every 5 minutes.  When I click the Run Now button it works but when I leave it to run, it does not run.  I have confirmed that the archive task is enabled.  Anyone have any ideas?

Thanks,

Andy
