Не добавляет балуны на карту в определённом городе.

Всем доброго дня. Сталкнуся с такой проблемой, помогите решить.

Не добавляет балуны в на карту при выборе "Нижегородская область" -> "Нижний Новгород" (ссылка на страницу)

 Ссылка на массив данных

 Ссылка на скрипт МультиГеокодера 

Ниже код инициализации, брал всё с API примеров.
