Date repeat API and Content Copy

HI there,
In one of my cck types I have a date field, in field's data settings :: multiple section I denoted that the field is "repeated" and every thing was okay, till I decided to export this content type and import it into other drupal installation to find that the imported date field has "Unlimited" choice marked instead of "repeat" in data settings.
- I'm using php 5.2
- here is an export of my date field:-

$content[type]  = array (
  'name' => 'Program',
  'type' => 'program',
  'description' => '',
  'title_label' => 'Title',
  'body_label' => '',

  'help' => '',
  'node_options' => 
  array (
    'status' => true,
    'promote' => true,
    'sticky' => false,
    'revision' => false,
  ),
  'comment' => '0',
  'forward_display' => 1,
  'old_type' => 'program',
  'orig_type' => '',
  'module' => 'node',
  'custom' => '1',
  'modified' => '1',
  'locked' => '0',
  'ant' => 0,
  'ant_pattern' => '',
  'ant_php' => '',
);
$content[fields]  = array (
  0 =>
