Empty Bullet in Navigation Panel

This is more of a question as to possible application behavior. Business Objects 4.1

I have a Webi which displays several groups in the navigation panel, each group name preceded by a bullet with 1 additional bullet added to the list ; one which is not associated with anything.

If I change the view to User Prompt, the following apperars:

with (-Show List of Values-) in the 'empty' Bullet Space. I noticed that clicking on the 'empty bullet' brings you to 'top of pager', that is, the top of the groups collection.

Is there any way to remove the 'empty bullet' or is this the expected behavior?

Thanks!
