biblatex-publist makes me coauthor of entries I'm not author of

When writing my cv, I wanna include some bibentries for my own papers, but also some other describing some courses I’ve taken. My strategy is to put those courses taken in a special class (e.g. @book) and print separate bibliographies as follows:

documentclass{article}

title{Curriculm Vitae}
author{R. Reventlov Giskard}

usepackage%
    [backend=biber,%
    style=publist]% 
    {biblatex}

plauthorname[R. Giskard]{Reventlov}

addbibresource{articles.bib}
addbibresource{courses.bib}

begin{document}

maketitle

nocite{*}

%   MY ARTICLES
printbibliography[title={Published Articles}, type=article]


%   COURSES [BOOKS] BY OTHERS
printbibliography[title={Courses Taken}, type=book]

end{document}

The printbibliography commands should print something like:

Published Articles

[1] 2006 (with R. Daneel Olivaw). "The Three Laws of Robotics Revisited".

[2] 2005. "The Zeroth Law of Robotics".

Courses Taken

[3] 2004 Susan Calvin. Practical Aspects of Robotics.

[4] 2003 Han Fastolfe and Vasilia Fastolfe. How to read and influence the emotions of humans and robots.

Instead, they fourth entry is mistakenly printed as follows:

[4] 2003 (with Han Fastolfe and Vasilia Fastolfe). How to read and influence the emotions of humans and robots.

How can I prevent biblatex-publist from implicitly making me coauthor of this fourth entry (or of all @book entries for that matter)?

Note 1

In my full code I declare a special entry type @course as follows:

DeclareBibliographyAlias{course}{book}

and then call:

printbibliography[title={Courses Taken}, type=course]

In both cases, the error persists.

Note 2

The output without style=publist would be something like:

Published Articles

[1] R. Reventlov Giskard and R. Daneel Olivaw (2006). "The Three Laws of Robotics Revisited".

[2] R. Reventlov Giskard (2005). "The Zeroth Law of Robotics".

Courses Taken

[3] Susan Calvin (2004). Practical Aspects of Robotics.

[4] Han Fastolfe and Vasilia Fastolfe (2003). How to read and influence the emotions of humans and robots.
