An .opf file is not an ebook which may explain why you are having a problem. Instead such a file only contains metadata about a book.

Have you tried opening the file in the Calibre Editor and running Check Book and then have Calibre automatically fix any errors found? I don't know if this will help, but I think it's worth a try.
