Services Path is missing fields

When I access my view using the path set in the display, some fields are missing. The preview for the display shows that the fields are missing as well. When I access the view directly (not using the path), all the fields are present and correctly formatted.

My view:

$view = new view();
$view->name = 'API';
$view->description = '';
$view->tag = 'default';
$view->base_table = 'node';
$view->human_name = 'API';
$view->core = 7;
$view->api_version = '3.0';
$view->disabled = FALSE; /* Edit this to true to make a default view disabled initially */

/* Display: Master */
