want changes to submenu applied to all submenus

I have tried that. Does not work. Also, it is not clear from exactly where I should do that. From my mouse on the offending menu? Mouse on one of the non-submenu items in the offending menu? Mouse on one of the submenus on the offending menu?

But, no matter where my mouse is when I right click to get Customize Menu, checking the box to overwrite the submenus does not reset their color schemes.
