Is /etc/rc.local called twice on boot?

As you can see it is being run twice.  The second one is the one that
should be there, which is the service rc-local.service, which is the
one that was made available when the automatic running of the script
was removed from Ubuntu.  I don't know where the first one is coming
from.  You should be able to stop the second one using
sudo systemctl disable rc-local

I am sure that google or   man grep  would tell you that much quicker
than asking here.
