siunitx 无法完美对齐表格中的范围

Question

我遇到的问题是，S类型列与间隔符号没有完全对齐。请参阅此 MWE：

\documentclass[final, 12pt, USenglish, a4paper]{scrbook}

% UNITS
\usepackage{siunitx}    %for properly using SI units
\sisetup{range-phrase={\hspace{0.08em}--\hspace{0.08em}}, range-units=single}

% TABLES
\usepackage{booktabs}   % formatting table lines: \toprule, \midrule, \bottomrule
%\usepackage{multirow}  % span table cells across multiple cells
\usepackage{caption}    % formatting captions
\captionsetup[table]{singlelinecheck=false, justification=justified}    % aligning table captions on the left
\usepackage[flushleft]{threeparttable}  % aligning tablecaptions and notes. wrap tabulars with it: \begin or \end{threeparttable}

\begin{document}
\begin{table}[ht]
    \centering
    \begin{threeparttable}
        \caption{Some MWE:}
        \label{tab:mwe}
        \begin{tabular*}{0.8\textwidth}{l|@{\extracolsep{\fill}}S}
            \toprule
            One column              & {Strength\tnote{1} / \si{\kilo\joule\per\mole}}       \\ \midrule
            aaa                     & \numrange{40}{360}                                    \\
            bbb                     & \numrange{40}{200}                                    \\
            ccc                     & \numrange{4}{50}                                      \\
            ddd                     & \numrange{40}{120}                                    \\
            eee                     & \numrange{4}{80}                                      \\
            fff                     & \numrange{0}{50}                                      \\
            ggg                     & \numrange{0}{20}                                      \\ 
            xxx                     & \numrange{4}{40}                                      \\ \midrule 
            iii                     & \numrange{160}{480}                                   \\
            jjj                     & \numrange{80}{320}                                    \\ \bottomrule
        \end{tabular*}
        \begin{tablenotes}
            \footnotesize
            \item[1] Bla
        \end{tablenotes}
    \end{threeparttable}
\end{table}
\end{document}

除第 iii 行外，符号–在各处均完美对齐，其中间隔突然明显160与 对齐80。有人知道如何修复此问题吗？我真的不知道从哪里开始。
