Article Suggestion not correct?

Hi Maverick,
just bought and installed Article Suggestions (plugin).
I have fully configured the plugin and noticed the following behavior:
1. upon 1st entry of the article the first tab (author articles) is displaying the articles of the second tab (related articles)
2. clicking tab 2 (related articles) doesn't change the article list
3. clicking on tab 1 (author articles) loads the correct contents.

you can see this behavior on my test website: http://xceed.no-ip.org/ll_test/ai-algemeen/276-anders-veranderen-volgens-thijs-homan

Hope it is an easy fix :), love this plugin :)
