Rida - couple of things to check
- have a look in Manage Authors for anomalies, I would anticipate you should see two authors
René Goscinny with Sort Name Goscinny, René
Albert Uderzo with Sort Name Uderzo, Albert
- have a look at where the Asterisk books are stored, press 'O' to open a Book folder. I would anticipate they'd all be stored in book title folders within the "Rene Goscinny" author folder (note the loss of the acute diacritic on the second 'e').
Maybe you have run up against a very obscure problem with path lengths. Create a fresh library at the root of a drive, then copy the Asterisk books to it using Calibre's Copy to library tool… by default it's in the book list context menu. Then try saving the Asterisk books to disk from it.
