[Tex/LaTex] Using the Subcaption package changes caption font

Question

I'm using the SIGCHI conference paper template, and having an issue with the subcaption package. When I don't include it, the template makes the figure captions look like this (the way they are supposed to):

But when I include it, the captions look like this (even if it's just a regular figure, not a subfigure):

I cannot figure out how to make the captions with the subcaption package look like they're supposed to for the template. Here's the MWE:

\documentclass[chi_draft]{sigchi}

\usepackage{subcaption}

\begin{document}
    \begin{figure}
        \centering
        \includegraphics[width=\linewidth]{figures/sigchi-logo.png}
        \caption{test}
    \end{figure}%
\end{document}

Any suggestions for how to force the caption font to the one specified by the template?

Answer 1

This looks fairly close.

\documentclass[chi_draft]{sigchi}    
\usepackage{subcaption}
\captionsetup[figure]{font={bf,small},skip=0.6\baselineskip, labelsep=period}
\begin{document}
    \begin{figure}
        \centering
        \includegraphics[width=\linewidth]{example-image}
        \caption{test}
        \label{fig:gps}
    \end{figure}%
\end{document}
