Alternative View Protection (optional / experimental)

I got to use a static page as home page where the blog posts are to be shown up on another page than the home page. Some artcles are restricted. If the funktion “Alternative View Protection (optional / experimental)” is checked no posts are shown up at all. I have to switch off the function to make posts visible. But then all the posts are to be seen including those that are restricted ones. Looks like a bug. What can I do to make only those posts appearing that are not restricted on that page? The web page is https://www.in-mediation.eu. The blog-page is https://www.in-mediation.eu/magazin/archiv
