Can't align angle values with siunitx in table

Question

I'm having trouble aligning angle values in my document with siunitx. The numbers are only aligned properly if I don't use the \ang{} command from siunitx. I made a small, minimum working example that shows the issue:

\documentclass[
    12pt,                                   
    DIV=12,                                 
    paper=A4,                                                       
    parskip=half,                                           
]{scrreprt}

\usepackage{booktabs}                       
\usepackage{tabularx}                       

\usepackage{siunitx}
\sisetup{locale = DE}


\begin{document}
    
\begin{table}[h]
\caption{Align the following numbers}
    \begin{tabularx}{\textwidth}{S[table-format=+2.2]}
        \toprule
        \textbf{Values} \\
        \midrule
        \ang{70,50}     \\
        \ang{40,50}     \\
        \ang{20,50}     \\
        \ang{-4,40}     \\
        \ang{0,50}      \\
        \bottomrule
    \end{tabularx}
    \label{tab:Test1}
\end{table}

\begin{table}[h]
    \caption{Align the following numbers}
    \begin{tabularx}{\textwidth}{S[table-format=+2.2]}
        \toprule
        \textbf{Values} \\
        \midrule
        70,50           \\
        40,50           \\
        20,50           \\
        -4,40           \\
         0,50           \\
        \bottomrule
    \end{tabularx}
    \label{tab:Test2}
\end{table}
    
\end{document}

Something like this?

\documentclass[12pt]{scrreprt}
\usepackage{booktabs} 
\usepackage[locale = DE]{siunitx}

\begin{document}

\begin{tabular}{ @{} S[table-format = -1.2 \unit{\degree},
                       table-align-text-after = false] @{} }
  \toprule
  {\textbf{Values}} \\
  \midrule
  70,50 \unit{\degree} \\
  40,50 \unit{\degree} \\
  20,50 \unit{\degree} \\
  -4,40 \unit{\degree} \\
   0,5  \unit{\degree} \\
  \bottomrule
\end{tabular}

\end{document}
