Date Picker Fromatter replaces any date widget in Views

That happens with several views.
I created a simplistic one that behaves the same:

$view = new view;
$view->name = 'test_dpf';
$view->description = '';
$view->tag = '';
$view->view_php = '';
$view->base_table = 'node';
$view->is_cacheable = FALSE;
$view->api_version = 2;
$view->disabled = FALSE; /* Edit this to true to make a default view disabled initially */
$handler = $view->new_display('default', 'Defaults', 'default');
$handler->override_option('fields', array(
  'field_date_value' => array(
    'label' => 'Date',
    'alter' => array(
      'alter_text' => 0,
      'text' => '',
      'make_link' => 0,
      'path' => '',
      'link_class' => '',
      'alt' => '',
      'prefix' => '',
      'suffix' => '',
      'target' => '',
      'help' => '',
      'trim' => 0,
      'max_length' => '',
      'word_boundary' => 1,
      'ellipsis' => 1,
      'html' => 0,
      'strip_tags' => 0,
    ),
    'empty' => '',
    'hide_empty' => 0,
    'empty_zero' => 0,
    'link_to_node' => 0,
    'label_type' => 'widget',
    'format' => 'default',
    'multiple' => array(
      'multiple_number' => '',
      'multiple_from' => '',
      'multiple_to' => '',
      'group' => 0,
    ),
    'repeat' => array(
      'show_repeat_rule' => 'hide',
    ),
    'fromto' => array(
      'fromto' => 'value',
    ),
    'exclude' => 0,
    'id' => 'field_date_value',
    'table' => 'node_data_field_date',
    'field' => 'field_date_value',
    'relationship' => 'none',
  ),
));
$handler->override_option('access', array(
  'type' => 'none',
));
$handler->override_option('cache', array(
  'type' => 'none',
));
$handler->override_option('items_per_page', 0);

After enabling DPF

$view = new view;
$view->name = 'test_dpf';
$view->description = '';
$view->tag = '';
$view->view_php = '';
$view->base_table = 'node';
$view->is_cacheable = FALSE;
$view->api_version = 2;
$view->disabled = FALSE; /* Edit this to true to make a default view disabled initially */
$handler = $view->new_display('default', 'Defaults', 'default');
$handler->override_option('fields', array(
  'field_date_value' => array(
    'label' => 'Date',
    'alter' => array(
      'alter_text' => 0,
      'text' => '',
      'make_link' => 0,
      'path' => '',
      'link_class' => '',
      'alt' => '',
      'prefix' => '',
      'suffix' => '',
      'target' => '',
      'help' => '',
      'trim' => 0,
      'max_length' => '',
      'word_boundary' => 1,
      'ellipsis' => 1,
      'html' => 0,
      'strip_tags' => 0,
    ),
    'empty' => '',
    'hide_empty' => 0,
    'empty_zero' => 0,
    'link_to_node' => 0,
    'label_type' => 'widget',
    'format' => 'default',
    'multiple' => array(
      'multiple_number' => '',
      'multiple_from' => '',
      'multiple_to' => '',
      'group' => 0,
    ),
    'repeat' => array(
      'show_repeat_rule' => 'hide',
    ),
    'fromto' => array(
      'fromto' => 'value',
    ),
    'exclude' => 0,
    'id' => 'field_date_value',
    'table' => 'node_data_field_date',
    'field' => 'field_date_value',
    'relationship' => 'none',
  ),
));
$handler->override_option('access', array(
  'type' => 'none',
));
$handler->override_option('cache', array(
  'type' => 'none',
));
$handler->override_option('items_per_page', 0);

I don't see much difference, however, the altered setting appears in the attached screenshot
Thanks

The issue has self healed at some point...
Thanks for taking care
