Slider not working on blog page

The photo slider is somehow not working with the blog page (just showing the three pictures of the gallery in a row) https://asia-ngo.de/news/ (second post). It works tough on the visual editor page. There isn’t any special CSS applied on that page.

The same slider works perfectly well on the home page (https://asia-ngo.de)(also second post) and on the post’s page itself (https://asia-ngo.de/tshangkha-central-school-paten-gesucht/).

Running WordPress 6.6.1. Mostly using Firefox web browser but behavior is the same with chromium based browsers.

Thanks for your help!
