Sysstats in Objectdock doesn't work

hi, i copied the complete structre of the systats into the Objectdock Folder, but i don't get the choice to add them.

stardock/objectdock/sysstats

then i tried

stardock/objectdock/docklets/sysstat

and it didn't work either. i only see the default docklets, which were pre-installed.

ObjectDock Version 1.20.520n Plus

Sysstats 2.5.8
