I have a book with 
mobi-asin:B0B8G1287N. 
When I download it with 
only Amazon for a source (along with title/author), it correctly picks up 
this book with the description.
If I 
also enable Goodreads, it combines the entries, but the description is now blank, presumably because the 
GR entry doesn't have one.
Is this a plugin issue, or should I file a Calibre ticket?
