I'm helping my professor format the citations of one of her papers. The desired format should be in a chicago style, and here is an example: 
It seems that "biblatex-chicago" package can easily achieve this, and I indeed make it using the following MWE:
\RequirePackage{filecontents}
\begin{filecontents}{test.bib}
@article{Mckinsey:2020,
author = {Tracy Nowski and Maisie O'Flanagan and Lynn Taliento},
title = {A Transformative Moment for Philanthropy},
year = {2020},
journal = {McKinsey \& Company Social Sector Practice Paper},
}
\end{filecontents}
\documentclass{article}
\usepackage[authordate,giveninits]{biblatex-chicago}
\bibliography{test.bib}
\begin{document}
\cite{Mckinsey:2020}.
\setlength{\bibhang}{0pt}
\printbibliography
\end{document}
However, I need to change the class file to this one RCFS.cls to satisfy the formatting requirements of the journal. But when I did so (just replaced \documentclass{article} with \documentclass{RCFS}), the dots and commas in author names suddenly disappeared. This is what it looks like:
Does anyone know how to fix this issue? I've been stuck with this for quite a long time. Many thanks!
biblatexsubmissions because the workflow forbiblatexis very different from the usual BibTeX workflow. Double check what the submission guidelines have to say about LaTeX submissions and bibliographies. I would only ever usebiblatexfor submissions if the journal guidelines explicitly recommend it. Some journals don't actually care about the finer points in the bibliography style as long as the references are complete and more or less consistent. Journal staff will apply the house style before publication. – moewe Apr 08 '22 at 05:48
