Add Statemachine adds annoying reference to Statemachine to diagram

[Geert Bellekens]

Since one of the newer versions, if you add a state machine to class it adds the statemachine, adds the state machine diagram, but then it also adds the statemachine to the diagram looking like a diagram reference.

Why is this happening all of a sudden? The feature was working fine as it was.

If it ain't broke, don't fix it!
I'll report it as a bug
