I've noticed that the pericope information used in the Logos edition of the NKJV doesn't match the printed versions that I have. I've compared quite a few chapters, but here are just two examples you can easily check: Matt 18 and Jn 1.
Is there a way Logos could give us the section headings actually used by Thomas Nelson, the copyright holder of the NKJV? I'm not sure where the current set came from but it doesn't match any of the 6 printed copies I own which include both really old and brand new editions.
