Affiliate Manual Payment Failed Credit

So I was testing the affiliates plugin for MarketPress with Manuel Payments.

When I did a test run of a purchase and referral, it did not acknowledge any income for the affiliate account. It shows that the user did in fact sign up, however it does not show that the user made any purchase after I marked the product the refereed user bought as paid under manual payment.

Am I missing something?

Also, if the user signs up via affiliate link, will any purchase they make go towards their affiliate income? Or is it only stored in cookies?
