If your portal is showing the same name in the BGO field, and in the admissions counselor field, and that name is the Region 8 Fleet and NAPS coordinator, but you are neither in the fleet nor are you at NAPS, then I would suggest there might be an error.
You asked above "Am I supposed to contact the BGO to setup an interview?" and "will the portal instruct me to do so?". The answer is yes.
If you read the instructions in the portal, right above the BGO name, it states:
"This is the contact information for your Blue and Gold Officer. You are required to contact this individual to setup an interview that will be included in your admissions file........"
If you have tried that and have been unsucessful, the best course of action, for someone who "anticipates getting accepted into the Academy", but who has not yet completed the application, would be to call the Admissions office on the telephone and ask to speak with the Admissions Counselor assigned to your state. It is easy to find the phone number
