Imageflow-Block on <front> misbehaving

Hi,
i've set up Imageflow as a block displaying project-nodes. It works fine except on the front page.

This page is working fine:
http://www.vernetzte-kirche.de/info/de/startseite
but:
when this page is set as homepage the node-text, breadcrumb and heading go missing
http://www.vernetzte-kirche.de/info

Does anyone have a guess what could be causing this?

Thanks
