Try this driver, see if it makes a difference: [DRIVER] Zooz Smart Plugs Advanced (ZEN04 / ZEN05 / ZEN14 / ZEN15)

Also, possibly you need to delete the attributes and let them be re-created with a proper driver. If you switch to the driver/type called "Device" there is a button to delete current state. Switch back to the normal driver and they will get repopulated as reports come in.
