Activity пересоздается после смены Activity

У меня есть 3 Activity. 1 - MainActivity, 2 - InfoActivity, 3 - ChangelogActivity. Если я нахожусь на 2 Activity и перехожу на 3, а затем обратно , то все нормально, но если со 2 перехожу на 1 и обратно , то 2 активити пересоздается и данные на нем теряются. В частности ProgreasBar обнуляется.

Немного кода который может быть полезен.
