Shouldn't these all be the same series?

So - the Baylor Handbooks seem to have 33 books. They are all type Bible Commentary. But their series names are 3 that I see:

Baylor Handbook on the Greek New Testament

Baylor Handbook on the Hebrew Bible

Baylor Handbook on the Septuagint

Now I checked - I did not mess with the series name lol - but in this case, as I verified for myself, the linked Baylor Commentary set will not flip from say OT to NT. Should all these books have the same series name?

Should all these books have the same series name?

The publisher produced them as 3 series - see Series – Baylor University Press (baylorpress.com)

If you want them to behave as a single series, you need to change to a user provided series name.
