Oscola LaTeX 软件包不会显示法律表格

Question

我有以下 LaTeX：

\documentclass[12pt, a4paper]{article}
\usepackage[utf8]{inputenc}

\usepackage[style=oscola, ibidstyle=uc, ibidtracker=true, backend=biber, indexing=cite]{biblatex}
\usepackage[style=british]{csquotes}
\addbibresource{/Projects/Agape Chambers/llm-a.bib}

\usepackage[splitindex, nonewpage]{imakeidx}
\makeindex[name=cases, title={Table of cases}]
\makeindex[name=legislation, title={Table of Legislation}]

\DeclareIndexAssociation{gbcases}{cases}
\DeclareIndexAssociation{encases}{cases}
\DeclareIndexAssociation{primary}{legislation}
\begin{document}    

\section*{Assessment of liability under the Occupiers' Liability Act 1957\footcite{ola1957}}

\subsection*{Is the Defendant on OCCUPIER of PREMISES?}

\printbibliography[
  nottype=commentary,
  nottype=jurisdiction,
  nottype=legislation,
  nottype=legal]

 \printindex[cases]
 \printindex[legislation]
 \end{document}

这是我正在使用的 bib 文件。

@Legislation{ola1957,
    Title                    = {Occupiers' Liability Act 1957},
    Entrysubtype             = {primary},
    Keywords                 = {en},
    Pagination               = {section},
    Shorthand                = {OLA 1957},
    Owner                    = {user},
    Timestamp                = {2018.11.13}
 }

但是，当我运行编译（使用 TeXStudio）时，立法表没有出现。有人能帮忙吗？
