Windows 10 Edge bookmarks not used for Search

I recently upgraded to Windows 10 and imported my IE11 bookmarks into the Edge browser. They are all there. But when I start typing in the (Edge) address bar, or in the Windows search box, it does NOT offer me any Edge bookmarks. It seems as if Search/Edge address bar is not considering them. Hence I checked my "Indexing Options" settings which in fact only show "Inteet Explorer History" besides the directories I configured. Since IE11 uses the Favorites directory I checked if that is included and it was. However Edge doesn't seem to use it, as I created a new Folder in Edge and it did NOT appear in the Favorites folder. Now I'm at a point where I can see why it doesn't consider my bookmarks, but I don't know how to change it. Any ideas?

thanks a lot for your help
