Ubuntu – Restore Missing “Settings” (gnome-control-center) Icon in Ubuntu 18.04

I have been running Ubuntu 18.04 for a couple of weeks. I upgraded from 16.04 and all went smoothly.

I am not sure what I changed, but this morning I noticed that the "Settings" Icon that launches gnome-control-center is missing from "Show Applications" and the applications menu as well. When I searched from "Show Applications" for gnome-control-center or just settings, nothing showed up.

So, I figured I must have accidentally removed it and figured a reinstall of the package would resolve the issue. I have searched and found several postings where this worked. I tried:

sudo apt install gnome-control-center

And then rebooted – which reinstalled the gnome-control-center and I could then launch it from the command line. However, there was still no Settings Icon in any of the menus.

I also tried many other suggestions including:

sudo apt-get install --reinstall gnome-control-center
sudo apt-get install ubuntu-desktop
sudo apt install ubuntu-desktop --reinstall
sudo apt-get install unity-control-center

However, none of these has been successful in restoring the icon into "Show Applications" or any applications menu.

Anyone have any suggestions on something I haven't tried? Would be much appreciated. Or, is there a way to just manually recreate the icon?

Output of locate gnome-control-center.desktop:

I am running Ubuntu 18.04 desktop on kernel 4.15.0-45-generic.
