ok it is showing what I would expect.
topics are shown only when you go into each forum which is standard bbpress behavior.
If you would like all the forums listed with titles, then create a WordPress page for your firums and put a list of forums in it as shortcode
[bbp-single-forum id=$forum_id] – Display a single forums topics. eg. [bbp-single-forum id=32]
so for instance out this on a page
[bbp-single-forum id=32]
[bbp-single-forum id=33]
[bbp-single-forum id=34]
.
