I wanted to write the bibliography I used for my master thesis. I grouped the references I used based on their type but my problem is that the references are not sorted.
My .bib file is this

I wanted to group my references based on their type (books, packages, master theses etc.) so I wroted this .tex file
\documentclass[inscr,ack,preface]{dithesis}
\usepackage[backend=bibtex]{biblatex}
\addbibresource{references.bib} %my .bib file is called references.bib
\begin{document}
%My document
% manually include the bibliography
\bibliographystyle{plain}
%\bibliography{references}
% include it also in ToC (do sth on your own)
\addcontentsline{toc}{chapter}{Βιβλιογραφία} %Βιβλιογραφία is the name of the chapter in Greek
\chapter*{\bibname}
\addcontentsline{toc}{chapter}{\bibname}
\begingroup
\let\clearpage\relax % Disable page breaks within this group
\printbibliography[type=misc, title={Μελέτες}] %for the studies
\printbibliography[type=online, title={Σύνολο δεδομένων}] %for the data source
\printbibliography[type=book, title={Βιβλία}] %for the books
\printbibliography[type=manual, title={Πακέτα στην R}] %for the packages in R programming languages
\printbibliography[type=thesis, title={Διπλωματικές Εργασίες}] %for master theses
\endgroup
%\nocite{*}
\end{document}
The output is presented in the following pictures first image second image. As you can see in these pictures the references are grouped but not sorted. What do you think I should do in order to keep them grouped and also sorted. I have searched a lot and I haven't found something useful yet. Can you provide me the LaTeX code?
