There are now 3 seperate menu items. They should be re-organised to become

/admin/config/devtrac
/admin/config/devtrac/settings 'IATI'
/admin/config/devtrac/import 'IATI Import'

Where settings is the default tab. Please use the special trick to get it in a block on the /admin page


  $items['admin/config/devtrac'] = array(
      'title' => t("Devtrac"),
      'description' => t("Devtrac Settings."),
      'position' => 'right',
      'weight' => -6,
      'access arguments' => array('administer site configuration'),
      'page callback' => 'system_admin_menu_block_page',
      'file' => 'system.admin.inc',
      'file path' => drupal_get_path('module', 'system'),
  );
