Почему oncreateview текущего фрагмента вызывается при нажатии кнопки «Назад»?

Я пытаюсь получить фрагмент из заднего стека. Он извлекается, но проблема в том, что при нажатии кнопки «Назад» также вызывается представление oncreate и последующие методы жизненного цикла текущего фрагмента. Вот мой код, чтобы поместить фрагмент в задний стек:

fragment=new FileTrackingFragment();
bundle=new Bundle();
bundle.putString("name","Dak Monitoring");
bundle.putInt("num",2);
fragment.setArguments(bundle);
ft.replace(R.id.parent, fragment, fragment.getClass().getName());
ft.addToBackStack(fragment.getClass().getName());
ft.commit();
break;

Вот код фрагмента:
