On a site (v3.5) using the Pianoforte template the frontpage has a category blog layout. There is some text above the content which is inserted in a module (contenttop) and which is assigned only to be shown on the frontpage . When you click on the articles in the blog layout, the contenttop text is also shown in these articles!
Furthermore, all the articles from the frontpage is also listed on a page with category list layout. When you click on any of these articles, the contenttop text is also visible here.
Why is the module shown on the articles in category blog layout and category list layout, and what should I do in order to deactivate the module in the articles?

See the problem live at http://repcomp.ibbi.dk on the frontpage and the menu 'Nyheder'.
