The usage of that toolbar is also a little strange. It actually gets "linked" to a profile or alignment when you right-click a profile or alignment and select "Edit geometry". So sometimes you might have it linked to one profile while you are trying to edit another profile. To keep from getting confused, it helps to close that toolbar as soon as you finish editing an alignment or profile, so you always open it fresh whenever you need it.
