Error editing connection: did not find a connection with UUID '(null)'

Multi tool use
I am a newbie to Ubuntu and I am trying to configure Ubuntu for a class. I have followed instructions that were given to me by my instructor. I am running Ubuntu 16.04 LTS from a VMWare mounted drive on a Windows 10 PC. When I first ran ifconfig -a, it did not display the connections correctly according to what should have been displayed from my instructions. I then proceeded to edit my /etc/network/interfaces file, to match the below:
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp
auto eth1
iface eth1 inet dhcp
However, now I am not sure if editing the interfaces file caused this issue, but now when I go to Settings, then Network, click on "Wired" Connection, then click "Options". I see this error:
Error editing connection: Did not find a connection with UUID '(null)'
What I should see is a UI window that allows me to edit the selected connection.
Not sure if it is related, but there are no DNS settings for the selected Wired Connection either.
This is what shows:
Hardware Address
IPv4 Address
IPv6 Address
Default Route
Apparently, this is what is expected:
IP Address
Subnet Mask
Default Route
DNS
Internet is working fine though I'm having this issue. This may be for an older version of Ubuntu, however, the UI should still open after clicking on "Options".
Any ideas?

Edit the file /etc/networking/interfaces and put a # in front of EVERY line. This will comment them out. NOTE you will need to use sudo and suggest command
sudo nano /etc/network/interfaces
Next, stop and restart the NetworkManager.service with:
sudo systemctl stop NetworkManager.service
sudo systemctl start NetworkManager.service
1
the start and stop of the network mnager should be two separate command - most easily done on two lines. First enter sudo systemctl stop NetworkManager.service on one line. Then enter sudo systemctl start NetworkManager.service on a new line
