Aura HD Recognize chapter, but not time stat!

Hi all, I have a problem with my kobo aura hd. The device recognizes the chapters and I can browse the index. This problem affects the reading statistics. Within the statistics shows me the percentage of completion of the chapter that corresponds to the percentage of completion of the book. As if there is only one chapter that throughout the book. In this way I do not show how much time remains to complete the chapter, I how much time remains to complete the book. Sorry for the English.
