标题中的作者所属上标未正确标记

Question

我非常恼火地尝试使用 Elsevier 文章类别对我的所属机构进行正确的编号。

\documentclass{elsarticle}
\usepackage{graphicx}
\usepackage{amssymb}
\usepackage{lineno}
\usepackage{multirow}
\usepackage{booktabs}

\journal{Prestigious Journal}

\title{Baldrick has a Clever Title}

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Add Authors
\author[add1]{Author1 \corref{cor1}}
\ead{[email protected]}

\author[add1]{Author2}
\ead{[email protected]}

\author[add2]{Author3}
\ead{[email protected]}

\cortext[cor1]{Corresponding author}

\address[add1]{School of Turnip Engineering}
\address[add2]{School of Sausage Engineering}

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

\begin{document}

\maketitle

\begin{linenumbers}
\begin{frontmatter}

\begin{abstract}
%% Text of abstract
Turnips go well with sausages.\\ 

\end{abstract}

\begin{keyword}
Turnips \sep More Turnips 
\end{keyword}

\end{frontmatter}
\end{linenumbers}
\end{document}

上标是错误的（但至少顺序正确）。我尝试了很多种变化。有什么想法吗？

如果不使用\begin{frontmatter}...\end{frontmatter}

\documentclass{elsarticle}
\usepackage{graphicx}
\usepackage{amssymb}

\usepackage{multirow}
\usepackage{booktabs}

\journal{Prestigious Journal}
