I've noticed that the ESV study Bible seems to be missing references to the introduction sections of Books of the Bible. If I open a Bible to the beginning of a book, such as Romans, The study Bible correctly follows to that section. If I scroll back up to the introduction of the Book in the Bible, the ESV Study Bible does not follow. If I do the exact same thing in the Reformation Study, it correctly jumps to the Introduction section. I'm assuming the milestones (I believe that is the correct term for this function) to the Introductions in the ESV are missing or broken. It would be nice to have these in place as now I have to scroll up multiple pages manually to scan this content.
