After purchase with affiliate link the total comission is $0.00

I need some help with the plugins “Affiliates Pro & Woocommerce integration” I recently purchased.

In WooCommerce settings I have a the default rate 0.1.
The test product has a rate of 0.5, set in the product page.

After a transaction is completed through an affiliate link (of the test product that has the referral rate of 0.5 for 50% commission), the amount shown in affiliates> totals is $0.00

As an affiliate I receive the emails, “A referral has been credited to you”.
But if I login with the affiliate account, the commission total is $0.00.

Here are my settings:

The Affiliates>Settings are:

1. “Referral Amount Method”

2. Affiliates_WC_Method::product_rate.

The Affiliates> woocommerce settings are

1. Enable product referrals (checked)

2. Default rate: 0.1

Thanks for your help!
