Try this way
Use PA's Account
Permanent Resident --> Family Class (Spouses)
Choose = Family Name, Given Name, Birth Date
Enter PA's Family Name, Given Name, Birth Date (I copy pasted Family and Given Names from the application file - not sure if that made any difference)
DO NOT put anything for city and country of birth (leave it BLANK Not even try to hit space bar just leave it empty)
Enter accurate Passport Information as it is on you application (I copy pasted the Passport Number - not sure if that made any difference)
Enter Province and City where PA intends to live (Enter as it is in your application)
Marital Status = Married
# of applicants = 2 (PA + Sponsor)
