Aeotec Smart Strip Child Devices Missing From Scenes

I am trying to build scenes for a Enerwave 7-button controller but the four switches from my Aeotec Smart Strip do not show up in the list of controllable devices. Other devices show up in the list and can be added and controlled by the scenes. Any ideas?

I also do not see a way to toggle each button on the controller. I can get the device to turn on with a push, but a second push does not turn it off.
