That's because the thread is closed. The closing thread sommary doesn't exist anymore because BertH is not a staff anymore, and it's not possible to close the forum thread without admin and discussion moderator right. BertH still have the staff right when he closed the thread, though. The wiki doesn't want to confuse how a user can close a forum thread without the "admin" or "discussion moderator" right, so the thread summary was removed, but the thread is still closed.
