Coupons not granting commission to tiers affiliates. Coupon tracking not working correctly.

Hi,

I have Affiliates enterprise installed with Woocommmerce.
We sell memberships and award our affiliates a flat rate of $75 per member that signs up through their link, or coupon code. We made coupon codes for the affiliates since they will not always be distributing links.

We have multi tiers enabled with only 1 tier. This is what we our affiliates to recieve:
Original Referrer = $75 commission
Tier 1 affiliate = $75 commission.

This works fine with normal affiliate links but does not when a coupon code is used.

The Coupon code is tracking both affiliates but only granting commissions to the O.R. See the screenshot in the link below.

How can I fix this?

Thanks in advance.
