Display of audiobooks in Author listing now fails to show books in iTunes 12.2.0.145

After my update to iTunes 12.2.0.145, the audiobooks in my library fail to display under my Authors listing. The sidebar shows the Authors, using the first audiobook thumbnail as an icon for that author, but the main display no longer shows all of the titles by that author, and thus, does not allow for selection of the title/part of the audiobook I wish to play while in that display mode. This is a definite coding error/regression.
