When I select the Projects or the Resources or the Proposals views, I find that other types of posts (such as Discussions) are also displayed in those views if the "Show posts form child groups you are a member of" button is deselected. When I select the "Show posts form child groups you are a member of" button, then only that post type is displayed. However, that button is supposed to be about child groups, not about including all post types in that view.
