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:

/usr/share/applications/gnome-control-center.desktop 
/home/dccrens/.local/share/applications/gnome-control-center.desktop
/home/dccrens/.gnome/apps/gnome-control-center.desktop

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

In my case I just ran

sudo apt-get install --reinstall gnome-control-center

rebooted the system, and it was restored. It is now working fine again.

Shortcuts in "Show Application" menu is shown by the Desktop Entry of the corresponding app. According to output of locate gnome-control-center.desktop, there are two extra gnome-control-center.desktop located in /home/dccrens/.gnome/apps/ and /home/dccrens/.local/share/applications/ which are creating the issue. Delete that files using Nautilus or rm /home/dccrens/.gnome/apps/gnome-control-center.desktop /home/dccrens/.local/share/applications/gnome-control-center.desktop.
