No function in Homepage widget area

Hello,

very nice and easy to handle theme, but I have one big problem.
When I put any (post)widget in the Homepage Widget Area, they have no function?!

In the middle homepage area, there are only the posts from 1 category, without any widget or rule-form behind?!

So, how can I get the big slider and the post widget in it, that there is a function of them?
