I went to read the Preface of the New King James Version, and there was no text at all, only little timeline flags. I realized it was because I have the Bible Text Only filter enabled in the bible to not show "Non-Bible text." I opened the NABRE, for which I also have the Bible Text Only filter enabled, and have the same problem.

I know that I can just temporarily turn the filter off to read the Preface, but I would think that the visual filters in the bibles would be designed to only impact the biblical text and not the frontmatter in the bible. Just because I don't want to see the very large bold distracting subtitles in the NKJV (I wish Logos would shrink those) doesn't mean I don't want to have access to the front matter in my bibles.
