No worries 
I forgot to add that if you want to control all the lights as a group, you can set them on the Alexa side. Or, if you want to achieve this on the OH side, you would need to give your group an item type. In that setup, the group would not be considered as a possible endpoint and all its members would be discoverable.
Group:Switch:OR(ON,OFF) gMyLights "My Lights" [ "Lighting" ]
