When a group has a Forum attached to it, does the Home tab

When a group has a Forum attached to it, does the Home tab for the Group never display any posts that are entered? If I open the group it shows the HOME tab and says "Whats new in .... Group" but then says, "Sorry, there was no activity found. Please try a different filter." the default filter is EVERYTHING .. but there is nothing displayed.

When I post something from the data entry box on this screen it appears to accept it but again, it does not display in the HOME screen.

If it is not supposed to display here when a Forum is attached to the Group, it should not display the tab / screen and there should not be a place to enter the post.
