Judging from some of the other stat blocks on recent units (such as the Arctic Trooper), it looks like someone at Z2Live was in a hurry and copy-pasted older unit info to use as a base for newer units. They changed all the most important and obvious stuff to make the new unit, but overlooked the Ability Slot field, resulting in units with more slots than abilities to fill them.

That's just my guess, though.
