Newly added galleries to articles using the gallery button plugin, are not showing up anymore in the fronted. Inside the editor windows of the article edit form, the gallery is shown correctly. But after saving and displaying the article on the website, the gallery is missing.
In the html source code, I can see the gallery. But the <picture> tag is missing a <img> element, therefore the thumbnail image is not shown.
If I am not mistaken, the <picture> tag requires an <img> tag as child, but this does not seem to be there.
Galleries which I added long time before using an older version of the component are still working as they are not creating the grid with the <picture> tag, but only with the <img> tags.

Between the line "Bildergalerie Vernissage von Samstag 14.06.2025 (Bilder: Andreas Busslinger)" and the portrait images, there is a showtime image gallery inserted into the article...
