PROBLEMA ORDINE BIBLIOGRAFIA CON SAPTHESIS

Salve, ho un problema con la bibliografia.
In particolare, segue un ordine tutto suo.

% !TeX encoding = UTF-8
% !TeX program = pdflatex
% !TeX spellcheck = en_US
\documentclass[binding=0.6cm]{sapthesis}
\usepackage{microtype}
\usepackage{hyperref}
\usepackage{graphicx}
…
\backmatter
\cleardoublepage
\phantomsection % Give this command only if hyperref is loaded
\addcontentsline{toc}{chapter}{\bibname}
\bibliographystyle{unsrt}
\bibliography{ref}
\nocite{*}
