Twitter Card Meta Tags are not displayed

My assumption is that this isn't a bug and that I'm doing something wrong... because the feature just isn't working at all and I'm not seeing a bunch of other issues about it not working... so hopefully you can help me figure out what I'm doing wrong.

Here is a page on my site:

Here is the export of the Node configuration, I believe the only thing I changed is that I set a creator value for my twitter account:

$config = new stdClass();
$config->disabled = FALSE; /* Edit this to true to make a default config disabled initially */
$config->api_version = 1;
$config->cid = '1';
$config->instance = 'node';
$config->config = array(
  'title' => array(
    'value' => '[node:title] | [site:name]',
  ),
  'description' => array(
    'value' => '[node:summary]',
  ),
  'og:title' => array(
    'value' => '[node:title]',
  ),
  'og:description' => array(
    'value' => '[node:summary]',
  ),
  'twitter:creator' => array(
    'value' => '@inadaydev',
  ),
  'twitter:title' => array(
    'value' => '[node:title]',
  ),
  'twitter:description' => array(
    'value' => '[node:summary]',
  ),
);

I created a new default metatag for content type App, here is the export:

$config = new stdClass();
$config->disabled = FALSE; /* Edit this to true to make a default config disabled initially */
$config->api_version = 1;
$config->cid = '2';
$config->instance = 'node:app';
$config->config = array(
  'twitter:image' => array(
    'value' => '[node:field_phone_screenshots]',
  ),
);

However, none of the twitter:card meta tags show up at all... what am I doing wrong?
