In any book that is divided into two or more parts (e.g. 1st & 2nd Kings, 1st & 2nd Peter, etc.) The passage guide and text comparison are unavailable. Thanks for the hard work, I love the progress that is being made.
It looks like you found a bug! I have entered a case in our bug tracking system and we will be addressing that issue by pushing out a fix in a future release.
Thanks,
