No filtering at all

Hi i created 3 filter groups with this module and assigned a workflow current state filter to each of these. If i select one of the filter groups in my exposed form then the url (http://[my-url]?composite_views_filter_group=[my-state]) is updated with the new filter criteria but the content is not filtered. Only the filter group is exposed not the single filters inside those. I also noticed that the select list jumps always back to "all" and not to the selected group.

Any idea there?
