I am trying to buy a rail away offer for the Appenzeller show diary and the Klee Museum at Bern - where I am supposed to get a discount on my admission with either my saver day pass or by buying the point to point rail tickets from the SBB website - but for each of those offers after I add the passenger details (either by selecting or adding) the ticket type has no options to select and date of journey and other details remain greyed out and unavailable.
I have tried multiple browsers, disabled VPN, deleted browsing history and allowed third party cookies but no luck.
The link to the Paul Klee offer is https://freizeit.sbb.ch/en/stories/museum-zentrum-paul-klee
The same problem occurs with the appenzeller show diary as well.
Is something wrong with those parts of the site.
