Interfaces not displayed for an instance

[stereotype]

I have a class with a number of ports, and the ports have different required/provided interfaces.

I drag the class into an Object or Composite Structure diagram, drop it as an Instance (Object).
In the Features window, I can select which ports that shall be visible, and they appear in the diagram.
However, when I click on one of the ports, none of the port's interfaces are shown in the Features window.

Am I doing something wrong?

(I am using EA 15)

I guess that's a bug you should report. V13.5 behaves the same way.
