CMS Articles display always on the forumhome
 

Ok, maybe I do something wrong but when I write a articles what I only want to display on a other section it display also on the forumhome.
I have make 3 sections and no category.
When I have write a articles I choose from the menu the section I want to use.
I thought that the sections can be use separate but maybe I'am wrong.
Can someone explain how I can write articles which are only display in the section I want and not also on the homepage?
