Addition of 's' in front of abbreviation when using plural

MWE:

#!
\documentclass[]{scrartcl} 
\usepackage{acro} 

\DeclareAcronym{nn}{ 
    short = NN, 
    long = {neural network}
} 

\begin{document}
    \Acp{nn}
\end{document}

When running this code I get an "s" in front of the abbreviation like "(sNNs)", while the expected behavior is "(NNs)".
