Content duplicating after adding field 'Comment Posted Date'

In one of my views, I have content duplicating after adding the field 'Comment Posted Date'. Here is my code. Any suggestions or help is greatly appreciated.

$view = new view;
$view->name = 'Blog_Surrette';
$view->description = 'Blog - Surrette';
$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('relationships', array(
