The standard Manual Payment does not cater for Family/Subscription Group very well. You'll notice the status stops at Awaiting Payment. It is expecting you to add the Payment Items (family members) manually.
The best way is described in procedure How to do manual payments for family/group subscriptions | Payments2Us User Manual | Payments2Us Manuals. Using the "Make Payment" Button on the Contact - select "Credit Card", then select Manual type of payment.
