Color change in editor is not reflected in the displayed scene

The qmlscene app is not responding to changes made in the main file with the editor.
I include two screen shorts.

The one screen shot shows the display of 3 color boxes.
The initial one I created using the design tool, and selected a custom color.
The second screen shot show the edit where I changed the color to "white".
However, the first screen shot was the result of running the updated file change.
The custom color is commented out and replaced with "white", but the display
kept the original color.

Not good.
