Hi!

I have created a Bibliography section in my document written in lyx. It uses a book layout.

For some reason it did start over again when I added some more entries. The new entries was made some time later than the first ones. I just went down to key-27 and hit enter. Then it started on key-1 again.

Does anyone know why it behaves like this?

The lyx code is below.
