Genios tab tries to find article called "undefined" when opening SHZ article #539

I am using Firefox 139 and BibBot v0.40.2 and use Hamburger Bücherhallen as my Library

When I open an Article in on shz.de, (e.g. https://www.shz.de/lokales/schwansen/artikel/bau-der-lindaunis-bruecke-fertigstellung-nun-fuer-2027-angekuendigt-48811255) the Genios tab that opens has the correct date and source as filter, but the title in the search bar is "undefined".
