Was there ever any resolution to this problem? I am having the same problem where advanced option (color) changes are non sticking after it has indicated that a change was successful.
Manage Advanced Options window, use drop down to change the color, message says the default option has been changed, click close and sometimes the default changes and sometimes it does not. Sometimes it appears to change, but changes back after a short delay.
A couple of times early on the change seemed to stick, but then when I clicked finish to close the MAO page, the option reverted to the original default.
