AnsPress 2.0 – Paging on question list does not work

I have my WP front page set to Static Front Page -> Questions.
I have about 25 questions in my test system and the page-navigation appears at the bottom of the questions list.
Though when I click on the next button or choose any page, the list keeps showing the first twenty questions (page 1).
The URL does change into for example http://localhost:8080/page/2/ but I see the questions of http://localhost:8080/
