Confusion with Color Scheme settings tab

When I expand the Color Scheme tab there is a Color Set dropdown, three text boxes meant to hold color codes, and a color wheel.

The three text boxes are blank regardless of which Color Set I choose. Is that the way it's supposed to work? I assumed choosing a named set would result in the colors from it being adopted. Simply selecting a style is insufficient, because the three text boxes are required. In attempting to use the color wheel to provide values for the three text boxes, I discovered that clicking it has no effect other than to show where it was clicked, i.e. there is no popup of the code for the clicked color and no text transferred to the text box.
