It looks like one of your books has comments formatted in Microsoft Word; perhaps the entire text of the book is in the comments field.

Try this:

• Preferences|Interface|Add your own columns
• Click 'Add custom column'
  • Lookup name: cid
  • Column heading: Calibre ID
  • Column type: Column built from other columns
  • Template: {id:0>5s}
• Click OK, restart calibre
• Isolate the book where the problem is occurring by searching for the calibre ID in the search box:
  

  #cid:15985

• Edit/remove the comments for that book
