WOL requires that we have a MAC address for the machine being woken up. Without that MAC address we won't know what machine to direct the WOL packet to via the subnet directed broadcast. Try adding the MAC to your CSV Import and see if that works. Enter the MAC address in the standard "00:AB:34:FA:54:CD" format. I think either colons or dashes may be used to separate each hex pair.
Thanks,
