What you are seeing is quite normal, and is the default Start-up screen when iClone first loads. The Scene contains nothing except the Preview Camera and perhaps 2 Lights. Since nothing is selected, iClone defaults to the Modify Tab for the Camera. As the Camera does not have any Materials, Physics or Motions there is only one Tab visible. As soon as you add an asset to the Scene, or open a saved Project and then select an asset, then the Tabs pertaining to that asset will be present.
