Hi Scott,
This is definitely not working as expected, is there any chance you could provide a little more detail? Are you running a 32bit or 64bit linux? If you could provide a screenshot that would help greatly.
It might help to verify the correct type of panel is created as some panels will not contain the same range of options in edit mode. For example when creating a new custom panel the "Blank Self-Contained Data Source Panel" should be showing all of the widgets while "Empty Canvas" will show less options.
