The bible commentaries in the screenshot continue to not show in the Passage Guide at all.
The bug is in the type - they should not be Bible commentaries as they have no Bible index.
The Life Lessons titles and the Reformed Expository volume on Ephesians are devotional Bible studies rather than commentaries.
The Medieval Tradition volume on Revelation is an academic study of medieval interpretations of Revelation.
I have opened tickets for these volumes to no longer be classified as Bible Commentaries.
The Christ in the Bible commentaries were recently re-classified as commentaries at user request. I will open a ticket for Bible Indices to be added to these.
@Joe McCune (Faithlife) devotional bible studies should have bible indexes as well, and typically do - especially when they are Logos Research Editions there is a valid expectation to have those (as well as fill-in-the-box fields).
To NB.Mick's point, the other 19 of the Reformed Expository volumes in the series are Bible Commentaries with bible indexes and show up in the Passage Guide.
The updates to the Christ in the Bible commentaries came through already. Thanks @Joe McCune (Faithlife)!
@Chris Heil @NB.Mick I have updated the tickets, mentioning your concerns:
The teams handling these cases will decide what changes should be made.
Thanks, Joe!
If I recall correctly, to have a Bible index (as opposed to simply being able to access by Bible reference) requires that the Bible references be in canonical order. There may have also been a density of references requirement. These rules do change without notification so I may be wrong.
