When I had a problem like that, it was permissions - the allowed
permissions on sudoers files are very strict.  It would have to have
had write permission to be edited, but you have to change it back to
read-only or it will be ignored.  This is what is needed:

  chown root:root /etc/sudoers
  chmod u=r,g=r,o= /etc/sudoers

Also, it is better to add things like that in a new file in the
/etc/sudoers.d directory rather than putting them directly into
/etc/sudoers.

If you read the comments at the top of the /etc/sudoers file, it tells
you that you should use visudo as root to edit sudo files, as that
handles the permissions properly.
