Anchor link ends in 'Page not found'

On top of the Accommodation page I created 5 images with Anchor links. When I click on the images it ends up in 'Page not found'. For Mountain Room this address was initiated and does not work: Similar effect for all the other images and settings.

I checked the Anchor setting at the target and it seems to be ok. If I test it with the Wordpress dashboard open, then it works.

Please help and fix it.
