Help with MS Edge and Favorites.

Marie <>

Please help!
Just recently on my desktop, Surface and Asus laptop I cann no longer navigate by first letter in the list of favorites. But I also have a Lenovo laptop and it works fine on that machine. I did not change anything in any of these which I believe could cause this behavior. In addition on the three, when invoking the ctrl, shift, O, I do not find the favorite manager, etc.
I am totally stumped by this and can find no reason for it.
