MultiCam/Excalibur 5

Is there any reason that when I add Excalibur to the toolbar , that when you do the add/remove (from the configure tool bar)thing that what I see in the dropdown choices are Excalibur, then cam1a/cam1b/cam1c/cam1d/cam2a etc? When I watch the video on Excalibur, the toolbar just shows for cameras - 1/2/3, for the 3 tracks, not any a/b/c/d/? Also, once I do the render, my icons disapear from the toolbar. They are still there, but the icons are gone. Only way you know that they are still there, is to put the mouse on top of them and that highlites them, but they are transparent.
