Edges' Top Sites won't stick!

Monday morning (5/15/2017), after MS updated prior to shutdown, my computer would not boot up come morning. I could only access boot options via F12 (long story) did a restore via back-up stored on an external Hdd. After got back up & running, the Top Sites icons in Edge browser had changed, only one that I had previously had was for Face Book. I changed them back to before the update, but only one (FB) remained as before. Closing Edge & reopening it all the other icons were back as before. The screen below may explain my dilemma. I’m thinking it has something to do with the updates.
I’ve spent 2 whole days trying different things & a dozen or so from Google searches, but to no avail. I had this issue with the top sites when I 1st upgraded to 10 from 7 last July. I found the top sites very handy for my purposes as I only visit maybe a dozen sites.

With my new refurbed Dell got the top sites figured out & working great. At first didn't like Edge, but have since changed my mind. Getting to know the new browser took some time; now comfortable with it.
