I’ve bought the book “The Nichomachean Ethics” by Aristotle (Penguin Classics). The book displays correctly in the Kindle app on my iPad. I imported the book successfully into Calibre using the KFX Import plugin. Attempting to convert to ePub fails with numerous lines similar to:
calibre, version 8.7.0

All other KFX books convert absolutely fine, so it’s something specific to this book.
I originally reported this on the Calibre bug tracker but was advised to post here instead.
