I make a bibliography divided into two parts using multibib with this code
\documentclass[a4paper,12pt]{scrreprt}
...
\usepackage{multibib}
...
\newcites{doc}{Documentation citees}
...
\begin{document}
...
\bibliographystyledoc{plain-fr}
\bibliographydoc{biblio}
\renewcommand\refname{%
R\'{e}f\'{e}rences g\'{e}n\'{e}rales}
\bibliographystyle{plain-fr}
\bibliography{biblio}
\end{document}
Currently I get this

But if I compile the document in Article mode I get this

Finally, I would like to have the rendering article mode in report mode.
