Well, the "Enbrighten" ones are really for the 4xxxx series devices. the 14xxx ones shouldn't be using Enbrighten branded drivers at all, and should all work with the in-box Generic Z-Wave Smart Dimmer/Switch drivers.
That said, I'll still go back and fix mine. I'm sure Bert is right and it is because I never updated the button events/support.
Summary:
12xxx series = Generic Z-Wave Dimmer/Switch
14xxx = Generic Z-Wave Smart Dimmer/Switch
4xxx/5xxx = Enbrighten
