Factbook issue: Dictionary of American Christianity not displaying in Seventh-day Adventist entry

I pulled up the Factbook article on "Seventh-day Adventists" and only three dictionaries with articles are listed in the dictionary section. I was surprised that the Dictionary of Christianity in America (DCA) wouldn't have an article so I opened it up separately and lo and behold, there is an article titled "Seventh-day Adventists" (the exact title of the Factbook entry).

I clicked the parallel resource button in the DCA and also saw entries from A Concise Dictionary of Theology, the Cyclopædia of Biblical, Theological, and Ecclesiastical Literature, the New Schaff-Herzog Encyclopedia of Religious Knowledge, and the Modern Catholic Encyclopedia. However, none of these dictionaries are showing up in the Factbook entry for Seventh-day Adventists.

Is this a bug? Were these dictionaries not tagged for the new Factbook? What would cause these dictionaries to be missing from the Factbook entry?
