I myself have experienced this, when I first created blogger / blogspot. Articles that I have posted very much without my knowing it are lost and sometimes only partially appear when next to the next page. Even though I have set the number of posts in either HTML or blogger settings itself, it still can't solve the problem that I'm experiencing.
