Interface vs Exposed Interface

[radirpok]

I'm trying to model the component structure of my system using Component and Composite Diagrams. The idea is that I can expose the interfaces of a component on the component diagram, and go into details in the composite. Then I want to connect the exposed interfaces to Requirements or Features (for example).
My problem is that I can put an Interface element inside a Component on the composite diagram, but then can only expose it on the component diagram so that I select my interface from a drop down list -> then EA creates another element for it. So I will have the <<interface>> element (from the composite diagram) and also the exposed interface element. That is two elements for one!
Also, when I try to connect a requirement or feature to this interface (on an other diagram) I have to link the Interface again manually.

I was hoping that once I create the Interface within the Component it is exposed automatically (but at least no new element is created for it).
Is it me who's doing something wrong or is it the way it's supposed to work? Thanks.
