Problems with referrals

Hi, I need some help, please.

All referrals (total of 9) from the only affiliate I have are marked as accepted and he is expecting to receiving his commissions.

The problem is that only 2 orders (from those 9) were completed (paid) by my costumers.

Apparently, Affiliates Pro plugin does not know that.

Am I missing something? I am using woocommerce extension.

Thanks for any help.
