@Jeremy Walker, @Andrew Hillaker, could you share with us the title of some of the resources where you are finding this problem?
Some specific examples where they are not showing up:
Severus of Antioch, The Sixth Book of the Select Letters of Severus Patriarch of Antioch in the Syriac Version of Athanasius of Nisibis, ed. E. W. Brooks, trans. E. W. Brooks, vol. II (London; Oxford: Williams & Norgate, 1903–1904)
Christopher Voke, Prayers of Great Traditions: A Daily Office (New York, NY: Bloomsbury Continuum, 2013)
Donald S. Whitney, Spiritual Disciplines for the Christian Life (Colorado Springs, CO: NavPress, 1991)
interestingly, it’s not as universal as I thought. The following all have contents showing up as expected:
Charles Spurgeon, 300 Sermon Illustrations from Charles Spurgeon, ed. Elliot Ritzema and Lynnea Smoyer (Bellingham, WA: Lexham Press, 2017)
James Stevenson and B. J. Kidd, eds., Creeds, Councils, and Controversies: Documents Illustrative of the History of the Church A.D. 337-461 (New York: Seabury Press, 1966)
Thank you. I had the problem with titles from Spurgeon and Bunyan, among others. It seems to have been fixed, for which many thanks.
