There might be a misunderstanding of what the Group feature does.
From the JMP help:

So it is designed to give you different density ellipses, which I don't see on your pictures. The dots are colored from the Iris data because the row states were already established. I worked with the Fitness data and the grouping worked fine once I asked for the density ellipses.
