I think that it's an intended behavior. When you tap on an item, SelectedItem gets the value of that item and this causes the gray coloring. Navigating to another page doesn't have anything to do with the item state.

You have to manually set SelectedItem to null when you navigate, if you want it to turn white again.
You could also try to set SelectionMode to None.
