So much for consistent author names
There's also Jerome == Jerome, Saint == Saint Jerome.
And Saint Patrick seems to have one book where 'Saint' is treated as a surname, while The Life and Writings of St. Patrick with Appendices, Etc. doesn't mention him as author at all.
Oh, and looking at your screenshot again, I don't think 'Martyr' is a surname either...
And Abélard should have an accent on the e. I currently have two Abélards in my library, because my PB has the name spelled correctly, and I refuse to corrupt it just because Logos has.
I can replicate this with John Chrysostom, but I can't with Dio Chrysostom. What are you using in the find field of the panel? They aren't the same person so I'm unclear why you're including it as a repeated name.
Mea culpa re: Dio Chrysostom.
The shot is of the library panel with a filter
The first one, that's gotten John Chrysostom wrong, is a Vyrso book. I bet it's that very same one that's gotten Justin Martyr and Abélard wrong as well.
EDIT: Your incorrect Abélard, that is; mine comes from another book.
It's not less of a surname that Chrysostom is.
