I have two Jevelin Pages. They work as onepagers. The menus work with anchors, but they also have to work from the subpage “impressum”. So I added in the menu settings for example “/index.php/#contact”. On one page it works fine. On the other page, the site is reloading after every time I choose one navigationpoint. So this is very disturbing on the main site (landingpage).
I hope you are well today and thank you for your question.
To make it work, instead of using relative URL in the menu like this /index.php/#kontakt please use absolute URL https://yoursite.com/#kontakt in every menu items.
