Você tem referências cruzadas nas entradas do babador.
Da documentação:
Se o número de entradas secundárias que fazem referência a uma entrada principal específica atingir um determinado limite, a entrada principal será automaticamente adicionada à bibliografia, mesmo que não tenha sido citada explicitamente. O limite é configurável com a
mincrossrefsopção de pacote ...
