[Cdash] Strange Behaviour with Build Groups

[Bill Lorensen]

I started to reassign some build groups on the itk dashboard (rainy
days in Ballston Lake). As I move builds from Nightly to Nightly
Expected, the build results disappear and reappear somewhat randomly.
I am moving them using the icons on the dashbaord and not the list
interface under project management.

For example, look at BillsBasement
