Unity Button Selected Color

So I updated to the latest version of Unity which is 2019.3.12f1 and I’ve noticed that the UI for button now has the selected color feature.

This was new and I’ve noticed that after I click a button the button color goes to the selected color and doesn’t highlight anymore as set in the highlighted color.

The only way to fix this was by setting navigation to None. Could someone please explain what’s going on here and why do I have to set navigation to None?

Have the same question really.
