getPropertyValue() not including base table if it's not already included

Having some trouble with the getPropertyValue() function, it looks like it's not including the base table if it's not already included in the query.

This works:

$query = new EntityFieldQueryExtra();
  $query->entityCondition('entity_type', 'node')
    ->entityCondition('bundle', 'co_file')
    ->propertyCondition('nid', 0, '>')
    ->fieldCondition('field_co_file_parents', 'target_id', $nid)
    ->getFieldValue('field_co_file_type', 'value')
    ->getPropertyValue('title');

This doesn't:

$query = new EntityFieldQueryExtra();
  $query->entityCondition('entity_type', 'node')
    ->entityCondition('bundle', 'co_file')
    ->fieldCondition('field_co_file_parents', 'target_id', $nid)
    ->getFieldValue('field_co_file_type', 'value')
    ->getPropertyValue('title');

and gives the error:

PDOException: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'node.title' in 'field list': SELECT DISTINCT field_data_field_co_file_parents0.entity_type AS entity_type, field_data_field_co_file_parents0.entity_id AS entity_id, field_data_field_co_file_parents0.revision_id AS revision_id, field_data_field_co_file_parents0.bundle AS bundle, field_data_field_co_file_type101.field_co_file_type_value AS field_co_file_type_value, node.title AS title FROM {field_data_field_co_file_parents} field_data_field_co_file_parents0 LEFT JOIN {field_data_field_co_file_type} field_data_field_co_file_type101 ON field_data_field_co_file_type101.entity_type = field_data_field_co_file_parents0.entity_type AND field_data_field_co_file_type101.entity_id = field_data_field_co_file_parents0.entity_id WHERE (field_data_field_co_file_parents0.field_co_file_parents_target_id = :db_condition_placeholder_0) AND (field_data_field_co_file_parents0.deleted = :db_condition_placeholder_1) AND (field_data_field_co_file_parents0.entity_type = :db_condition_placeholder_2) AND (field_data_field_co_file_parents0.bundle = :db_condition_placeholder_3) ; Array ( [:db_condition_placeholder_0] => 163584 [:db_condition_placeholder_1] => 0 [:db_condition_placeholder_2] => node [:db_condition_placeholder_3] => co_file ) in field_sql_storage_field_storage_query() (line 585 of /home/data/drupal/installations/co/codev2/modules/field/modules/field_sql_storage/field_sql_storage.module).
