Error: Too many index entries

I'm tryng to convert from EPUB to AZW3 the ebook "Bibbia 2008 CEI", but I've got the error.

Is important for me to reach a index with le list of the books AND the list of the chapters of each book, but I think Calibre is trying to put every verse...

Somone can :help: me ?
