When using biblatex with style=apa:
\documentclass[12pt]{scrreprt}
\usepackage[style=apa,backend=biber,language=english]{biblatex}
\addbibresource{literatur.bib}
\begin{filecontents}{literatur.bib}
@conference{abc,
author = {A Author and B Author},
editor = {A Editor and B Editor},
year = {2010},
title = {{Title}},
booktitle = {Conference title},
publisher = {Springer},
address = {Stuttgart}
}
\end{filecontents}
\begin{document}
\nocite{*}
\printbibliography
\end{document}
Adding a Conference type bib entrance creates output that repeats the editors many times:
Expected output:
Author, A. & Author, B. (2010). Title. In: A. Editor & B. Editor (Eds.), Conference title. Stuttgart: Springer.
How to make it output the correct format?
Also there should not be a , before the & befor last authors.
