Problem with Quarto citation: referencing of book sections

Question

I use Quarto for scholarly writing and I have a problem with the citations. I've noticed that the referencing of book sections doesn't work when I use a custom citation style (csl: *.csl). If I choose a citation style with bibliographystyle: apa, however, there are no problems.

For an example, see the image. This is the entry in Zotero. The output with bibliographystyle: apa is:

If I import this entry with Quarto/RStudio into my script (better: into bibliography.bib file), the bibtex:

@inbook{beck2020a,
    title = {Ein Tabu mit gewaltigen Konsequenzen. Geschlechtsbasierte personale Gewalt in politischen Institutionen},
    author = {Beck, Dorothee},
    editor = {Beck, Dorothee and Henninger, Annette},
    year = {2020},
    date = {2020},
    publisher = {Ulrike Helmer Verlag},
    pages = {165--188},
    series = {Reihe Geschlecht zwischen Vergangenheit und Zukunft des Zentrums für Gender Studies und Feministische Zukunftsforschung der Philipps-Universität Marburg},
    number = {Band 9},
    note = {OCLC: on1204200688},
    address = {Rossdorf},
    langid = {ger eng}
}

There is the first bug: obviously the booktitle is not part of the bibtex, although it's part of the database entry.

The second bug is that even if the booktitle is in the bibtex, it's not expressed in output if I use a custom citation style via csl: *.csl. At the same time, it's not a bug of the citation style, as it works in MS Word -- the program I was working with before I discovered Quarto.

This solution does not work for me, because Better BibTeX doesn't work: Problem with Quarto automated referencing of book sections
