HVDC Transmission Link ETAP

I have been using etap 7.5 demo and have been trying to model an HVDC link connected to 2 buses and conduct a load flow analysis (there is also a generator in swing mode attached to one bus and a normal transmission line connecting the two buses to satisfy the simulation requirements), but it comes up with a pop up error saying calculation error "Calcluation aborted due to HVDC rectifier output or Inverter input kV not matching rated kV".I am unsure of what settings to use for the ratings page for the HVDC link. The busbars I am connecting to are set to 400 kV.

Does anyone have an example of settings for the HVDC link ratings page that would allow this to operate ?

Thanks
