Hi Hraban ! Would this approach be better for solving your problem: why not define the headers *once* and *only* worry about setting the marks? At the beginning of each chapter, the section mark is explicitly set to "*reset*". % ---MWE (only setup marking and setup headers) -------- % On s'assure que chapitre/section produisent bien des marks exploitables. \setupmarking[chapter][state=start] \setupmarking[section][state=start] % Fallback : si le mark de section est vide, on affiche "?" \def\SectionOrQuestion{% \doifelseempty{\getmarking[section]}{?}{\getmarking[section]}% } % --- Headers------------------------------------------------- % Page paire (gauche) : chapitre | numéro % Page impaire (droite): numéro | section (ou ?) \setupheadertexts [\getmarking[chapter]][\pagenumber] [\pagenumber][\SectionOrQuestion] % --- Chapters ------------------------------------------ % Point clé : au début de chaque chapitre, on "vide" la section, % pour éviter la rémanence de la dernière section du chapitre précédent. % Key point: at the beginning of each chapter, the section is “cleared” % to avoid any lingering effects from the last section of the previous chapter. \setuphead[chapter][ page=leftempty, before={\resetmarking[section]}, ] Then : re-set only marks instead of headers. What do you think ? Best//JP Le 26/12/2025 à 16:39, Hraban Ramm a écrit :

Hi, I found a solution for this problem, but I think it’s ugly, because I re-setup the header texts all the time. Is there a better (more elegant…) way?
