bfhTblr : ! Undefined control sequence. <argument> \g__tblr_defined_hdash_styles_prop

Hi,

the following example fails to compile

\documentclass[10pt]{bfhbeamer}

\LoadBFHModule{tabular}
\usepackage{tabularray}

\begin{document}
\begin{frame}
\begin{bfhTblr}{colspec={X[r]X[r]X[r]X[r]}}
$w_{ij}$ & $s_i$ & $s_j$ & $w_{ij} s_i s_j$\\
-1 & -1 & -1 & -1 \\
+1 & +1 & +1 & +1
\end{bfhTblr}
\end{frame}
\end{document}

with the relevant log output

\g_tblr_level_int=\count356
\g__tblr_data_row_key_count_int=\count357
\g__tblr_data_column_key_count_int=\count358
