I'm not sure I understand from your description what your problem is. Are you expecting a similar style of navigation in the authoring environment to be in the actual, final, course? There is an indication of what groups the learner is in just under the navigation - there should by a breadcrumb under the next,back,coursemap, etc. buttons that indicate the course, group, and screen name along with the page number.
I'm not sure if this answers your question. If not, could you please elaborate?
