Drupal - where has the Google ID disappeared?

On most of the sites I'm running the Google analytics ID is appearing.  Therefore, tracking and capturing data.  All except one!

Discovering where Google ID and Google Tag ID were on a client's site... or not in this situation.  Yes that's correct, for some reason the analytics IDs aren't appearing.  Zip, zero... nothing.

Looking on this site, Google tag Manager positions the tag ID in the following lines of code
