Btw I noticed something which I am not sure is related to the issue, but maybe can help with the research.
When I add a dynamic page from the collection options and the dataset is automatically connected to that page after that when I try to add a Filter the options for Value source are grayed out.
But after that if I add the same dataset to the same page (now I have 2 equal datasets in that page) the options for Value source are available for the second additionally added dataset. And now I can create all Filters which I want, but cannot connect it to the page
