Scott -
I am not aware of any issues like this. The version of the step type should not make a difference. Basically the Default Step Name Expression on the General tab of the Step Type Properties dialog box defines the name of the step at insert time.
Could you append a sequence with the step type in it?
Could you specify what you got in TS 2.x and now what you get in 3.0 for the step name when you insert a new step?
