For some reason my original post has been deleted, so I'm opening a new one. I had noted that the default color class grouping could not be set when the "apply" check box was not checked. This appears to have been corrected, but contact sheets still do not open to my default setting which has the "apply" checkbox unchecked. If I select "Restore defaults" from the right click menu, the correct defaults are applied including the unchecked "apply" checkbox.
