Healthcare.gov: English well speeched here

After telling Healthcare.gov who is in my household and which people I want to insure,  it asks me if I want to add the people I already entered into the system.

Add these people to what?

It tells me that I am not applying for insurance for a person and then asks "Is this information correct?"  The information is correct. I do not want to apply for coverage for the person listed.

The "Yes" option adds "I want to add this person".

The "No" option adds "I want to change this information."

I have already added this person to the application as a household member who does not need insurance. How should I answer this question?

Is it asking if the information I've already provided is correct or is it asking if I want to add this person as one seeking insurance?

Does answering "Yes" add them to the application as one I want to insure as the provided answer suggest? Or does answering "Yes" mean that the information I previously provided -- that they are not applying for insurance -- is correct?

Then, what does the "Cancel. I don't need to add this person" option do?

I am confused.
