Content Template no longer displaying new nodes. Works fine for older nodes
The module's page explicitly states: 


  NOTE: This module may be deprecated in Drupal 7! Here's your reason,
  basically the theming changes in D7 mean the field theming gets bound
  a lot lot later in the process, so it's not possible to generate the
  output into a Textarea for you to edit


In fact the module has been marked as deprecated and not updated since 20 September 2011.

Also there is a long discussion on https://www.drupal.org/node/1285558 about better ways of doing things without Contemplate module.

So it's just time for you to give up the deprecated module and re-code your template files as it simply won't work with later versions of Drupal 7.
