Consider this example of an elsarticle template:

\documentclass[3p,times,twocolumn]{elsarticle} \journal{Nuclear Physics B} \begin{document} \begin{frontmatter} \title{Sample article to present \texttt{elsarticle} class\tnoteref{label0}} \tnotetext[label0]{This is only an example} \author[label1,label2]{Author One\corref{cor1}\fnref{label3}} \address[label1]{Address One} \address[label2]{Address Two\fnref{label4}} \cortext[cor1]{I am corresponding author} \fntext[label3]{I also want to inform about\ldots} \fntext[label4]{Small city} \ead{author.one@mail.com} \ead[url]{author-one-homepage.com} \author[label5]{Author Two} \address[label5]{Some University} \ead{author.two@mail.com} \author[label1,label5]{Author Three} \ead{author.three@mail.com} \begin{abstract} Text of abstract. Text of abstract. Text of abstract. Text of abstract. Text of abstract. \end{abstract} \begin{keyword} example \sep \LaTeX \sep template \end{keyword} \end{frontmatter} \end{document}

where the footnote superscripts are not shown:

I tried replacing fnref with footnote now it shows the annotation, how ever it keeps incrementing even when referring to the same footnote! for example changing the below lines:

\address[label2]{Address Two\footnote{label4}} \address[label5]{Some University\footnote{label4}}

yields:

which is obviously wrong. I would appreciate if you could help me know how I can fix this.

P.S. link to the Reddit post.
