If you copied the *whole* unit from /lib/systemd/system/foobar.service
to /etc/systemd/system/foobar.service, then you have been using the
override system the wrong way.

The correct (and documented) way is to

1) create /etc/systemd/system/foobar.service.d/
2) put your overrides and *only* your overrides into
   /etc/systemd/system/foobar.service.d/somename.conf

Or, starting with Stretch, you can just do "systemctl edit
foobar.service" and it will do the right thing for you.
