I have a reference from a book, for which the bibtex input is

@incollection{weisberg_2006,
  author      = {{Weisberg}, M and {McCoy}, T and {Krot}, A},
  title       = {Systematics and Evaluation of Meteorite Classification},
  booktitle   = {{Meteorites and the early solar system II}},
  publisher   = {University of Arizona Press},
  address     = {Arizona, USA},
  year        = {2006},
  pages       = {19-52},
  chapter     = {2},
  editor      = {Lauretta, D. and McSween, H.},
}

And a MWE like so

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[style=apa,backend=biber,maxcitenames=1]{biblatex}
\addbibresource{ref.bib}

\begin{document} 

in book \parencite{weisberg_2006}

\printbibliography

\end{document} 

However when I call this reference with biblatex it is repeating the editors in the bibliography like shown below. Does anyone have any idea how it would be possible to change this so the editors are only mentioned once. Thanks!

Weisberg, M., McCoy, T., & Krot, A. (2006). Systematics and evaluation of meteorite classification (D. Lauretta & H. McSween, Eds.). In D. Lauretta & H. McSween (Eds.), Meteorites and the early solar system II. Arizona, USA, University of Arizona Press.

    Not related to the issue, but author = {{Weisberg}, M and {McCoy}, T and {Krot}, A}, should be author = {Weisberg, M. and McCoy, T. and Krot, A.},. Family names usually don't need brace protection and given name initials should be ended with a dot.

    What version of biblatex-apa are you using? With v9.8 (2020/04/06) I get "Weisberg, M., McCoy, T. & Krot, A. (2006). Systematics and evaluation of meteorite classification. In D. Lauretta & H. McSween (Eds.), Meteorites and the early solar system II (pp. 19–52). Arizona, USA, University of Arizona Press.", which looks much better.

    See github.com/plk/biblatex-apa/issues/86, the problem is fixed in v9.3 (2019/12/21). Update biblatex-apa.

This was a bug in versions 9.0 to 9.2 of biblatex-apa. It was reported in https://github.com/plk/biblatex-apa/issues/86 and fixed shortly afterwards in biblatex-apa v9.3 (2019/12/21).

With v9.8 of biblatex-apa I get

\listfiles
\documentclass[british]{article}
\usepackage[T1]{fontenc}
\usepackage{babel}
\usepackage{csquotes}

\usepackage[style=apa, backend=biber]{biblatex}

\begin{filecontents}{\jobname.bib}
@incollection{weisberg,
  author      = {Weisberg, M. and McCoy, T. and Krot, A.},
  title       = {Systematics and Evaluation of Meteorite Classification},
  booktitle   = {Meteorites and the Early Solar System {II}},
  publisher   = {University of Arizona Press},
  address     = {Arizona, USA},
  year        = {2006},
  pages       = {19-52},
  chapter     = {2},
  editor      = {Lauretta, D. and McSween, H.},
}
\end{filecontents}
\addbibresource{\jobname.bib}


\begin{document}
\cite{weisberg}
\printbibliography
\end{document}

Weisberg, M., McCoy, T. & Krot, A. (2006). Systematics and evaluation of meteorite classification. In D. Lauretta & H. McSween (Eds.), *Meteorites and the early solar system II* (pp. 19–52). Arizona, USA, University of Arizona Press.

APA aficionados may have noticed that the location should not be printed. This will be fixed in v9.9 of biblatex-apa: https://github.com/plk/biblatex-apa/issues/95.

Packages like biblatex-apa rely on users reporting deviations from the desired style.
