If you have not yet created separate room groups, the dialog includes as default the room group All rooms, which includes all rooms of the project. You cannot deactivate any rooms in the All Rooms room group.

Double-clicking on <New Room Group> creates a new room group. In the Active column, you can activate the desired rooms for this room group.
