KYLE: Series name questions and errors

In light of this post:

Don Awalt said:

The Book of Deuteronomy Chapters 1-11 by Arnold that was just released yesterday, has the wrong series name. Everything else in this Eerdmans Commentary set has a series "New International Commentary on the Old and New Testament"; but the new Deu book has the series name "New International Commentary on the Old Testament".

1. Why aren't the American Commentary on the New Testament and the American Commentary on the Old Testament merged as American Commentary on the Old and New Testament?
2. Same question re: Herders Theologischer Kommentar zum Alten/Neuen Testament?
3. Same question re: Holman New/Old Testament Commentary
4. Same question re: Poor Man's New/Old Testament Commentary
5. Same question re: Reading the New/Old Testament (series)
6. Same question re: T&T Clark Study Guides to the New/Old Testament
7. Same question re: The Two Horizons New/Old Testament Commentary
8. Same question re: Zondervan Exegetical Commentary on the New/Old Testament 
9. Inconsistent series naming - at least 4 volumes are in the series "Reading the Bible Today" while 21 volumes are in "Reading the Bible Today Series". These should be combined.
10. Re: Shepherd's Notes: Mason, John G. Luke: An Unexpected God. Edited by Paul Barnett. Second Edition is in its own series because of a difference in apostrophe type.
11. The series The Short Course is split into two because some resources include "series" in the series name and some don't.
12. The series Wisdom Commentary is split into two because some resources include "series" in the series name and some don't.
