Chapter number is missing

[colombojrj]

Hello,

The chapter number disappears when I add the following code to the cls file:

\ifdefstring{\ELEGANT@lang}{ptBR}{
  \RequirePackage[brazil]{babel}
  \setlength\parindent{2em}
  \newcommand\figref[1]{\textbf{Figura}~\ref{#1}}
  \newcommand\tabref[1]{\textbf{Tabela}~\ref{#1}}
  \renewcommand{\chaptername}{Capítulo \thechapter}
  \renewcommand{\partname}{\color{structurecolor} Parte}
  \newcommand{\authorname}{\textbf{Autor: }}
  \newcommand{\institutename}{\textbf{Instituto: }}
  \newcommand{\datename}{\textbf{Data: }}
  \newcommand{\versionname}{\textbf{Versão: }}
  \newcommand{\notename}{Nota}
  \newcommand{\proofname}{Prova}
  \newcommand{\problemname}{Problema}
  \newcommand{\definitionname}{Definição}
  \newcommand{\theoremname}{Teorema}
  \newcommand{\axiomname}{Axioma}
  \newcommand{\postulatename}{Postulado}
  \newcommand{\lemmaname}{Lema}
  \newcommand{\propositionname}{Proposição}
  \newcommand{\corollaryname}{Corolário}
  \newcommand{\examplename}{Exemplo}
  \newcommand{\exercisename}{Exercício}
  \newcommand{\remarkname}{Observação}
  \newcommand{\assumptionname}{Premissa}
  \newcommand{\conclusionname}{Conclusão}
  \newcommand{\solutionname}{Solução}
  \newcommand{\propertyname}{Propriedade}
  \newcommand{\introductionname}{Introdução}
  \renewcommand{\appendixname}{Apêndice}
  \newcommand\bioinfo[2]{\gdef\@bioinfo{\textbf{#1}: #2}}
  \newcommand{\updatename}{Atualizações:}
  \newcommand{\historyname}{Histórico de versões}
}{\relax}

Please help.

sorry, this problem is caused by the \chaptername re-definition, I update the logic, but it still in test stage, you can try the latest version of elegantbook.cls (download from dev branch, and place this file in your project folder), add you language settings according other language settings.).
