‘Site View’ menu doesn’t match that in Editor/Customize view

I have customized the background for the selected page in my primary menu in Crio via:

Appearance/Customize/Design/Menus/Main Menu/Menu Items/Active Link Style/Background Color/

The color is set to a gray.

If I select a top-level page on the menu, the selected top level menu item has, as desired, a gray background in both Editor/Customize View and Site View.

If I select a second level page on the menu, the Editor/Customize View shows the desired gray background for the selected second level menu item AND the associated top-level menu item. But in Site View, only the associated top-level item has a gray background, i.e., the selected second level menu item remains white.

How do I get the Site View to match the Edit/Customize view?
