I will also reiterate that the global part full design parameter can still impact the "capacity (excess design)" result. If you change this, it will change the way that this result is calculated, for all pipes (except those with local design constraints), regardless of whether they are being designed and regardless of whether calculated flow and physical parameters are the same. As Scott mentioned, if this does not help, having a copy of the model with details of what to change to observe the issue would be helpful and enable us to give you a more specific answer.
