title_body: Why/Where is calibre writing author/title in metadata when saving to device? When I connect my device Simple Touch Nook, I send a book to my device using the calibre management software. Although I have the template {title} - {authors} set for sending to device, when I open the Library in the Nook (now unplugged from my computer), I found {authors}/{title} as the title of the book.
  
  I don't know why/where is calibre doing this. It's not documented, not defined and not wanted.
  
  I want to have {title} as the title of my book in Nook's library.
upvoted_answer: I had trouble with metadata from Calibre until I realised that I had to either reconvert or polish the ebook after making any changes to the title, author, description etc. 
  
  For the metadata to "stick" you have to polish (in the case of an epub) or convert (in the case of a new book in other than epub format).
  
  Although the metadata will look fine in Calibre, if you've made changes you need to polish or convert for the changes to be applied to the ebook.
  
  Hope this helps you.
