I have had problems adding books between MacIntosh and Windows versions of Calibre. When I try to add a book into my Windows Ebook Library from a folder with a book, cover and metadata from a Mac version of Calibre the book is imported but neither the cover of the metadata is.
If I then open the Mac created folder and copy the opf file and cover into the Windows library folder the cover appears and some of the metadata - but not the description.
I have seen the same problem when trying to add books from a Calibre Windows library folder into a Mac Calibre Libray.
Does anyone know how to work around this or have any explanation of why this is happening? I am using Calibre 8.18 (downloading the newest one now).
