TeX/Latex - Problema bibliografia

Estoy realizando un trabajo y citando utilizando el parámetro \cite{nombre_de_la_cita}. Sin embargo, sólo me aparecen algunas referencias y no todas.
Aparentemente no parece un error del código de la bibliografía ni de los parámetros que cada referencia bibliográfica tipo debe contener.

Os dejo por aquí todas las referencias bibliográficas. Las únicas que sí aparecen en mi compilación son la referencia 17, 32, 34 y 35:
