In the past, somehow (and I have seen it on systems of mine) it has been possible to end up with an empty row of data in the "DHCP Static Mappings for this Interface" in Services->DHCP. I am unable to replicate how this happens, I tried on VMs of systems back to 2.3-RELEASE with no "luck".

When this happens, Status->DHCP Leases correctly does not show the empty entry. But it does get the array index for subsequent entries wrong. So if you click the edit button to edit the entry for a row, it takes you to the wrong entry.

That can easily be fixed.

From Services->DHCP Server, such entries cannot be deleted. I think the underlying delete code only actually performs the delete if the entry is non-empty. I guess that should be fixed also.

Ideally it would be good to find how this can occur in the first place. Once understood, then that can be fixed (if still a bug in current code) and an upgrade step put in place to cleanup empty entries.
