In the KJV Study Bible > Between the Testaments > Introduction to the New Testament, the entire paragraph "The New Testament in its Historical Setting" is REPEATED TWICE (ie three copies of the exact same thing). I own the hardcopy of this ... there is only one instance of this paragraph, which ends that NT Intro section.
I'm not sure where to go to report this for a fix. It's not a suggestion, its ERRATA.
