This is not a bug in CC. It is how calibre devices have worked for my 8 years of being a calibre developer. Books are matched by calibre using their file name on the device, something that is built very deeply into calibre and will not change. The file name is controlled by a template, and in CC's case also by a CC-side template. Neither CC nor calibre know that you did a presto-chango and created a new book that has the same device file name as the old one.

If you want books to change when their calibre book ID changes then you must add the book ID to the file name used by the device.
