Автозаполнение Google Maps Places неправильно заполняется при использовании кнопки «Назад»

У меня есть простая адресная форма для адреса. Когда я перехожу на следующую страницу и затем нажимаю кнопку «Назад», данные адреса искажаются. Адрес отсутствует, в поле address2 указан город, в поле city указан почтовый индекс, а почтовый индекс отсутствует...

Если я уберу скрипт google maps внизу, все работает нормально, но включив его, я получаю ошибочное поведение. Я максимально упростил автозаполнение и даже удалил часть fillInAddress() для автозаполнения. Не знаю, куда идти отсюда. Любая помощь приветствуется.
