Column separator shown even when first field is blank

I have a view that shows two content types. One of the content types has a node referrer cck field pointing to a third content type. I have the view set to show the title from the referred content type followed by the original title. The problem is that when the other content type shows, the separator shows even though there is nothing in front of it.

I am assuming I am doing something wrong, but this may be a bug.

The view:

$view = new view;
$view->name = 'tune_refer';
$view->description = '';
$view->tag = 'Node Body';
$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');
