Store credit being given for non coupon-affiliate coupon

hi

So I use automate-woo to send some coupons out post purchase. Someone bought something using one yesterday. In the Dashboard of your (excellent) plugin, its awarded my “super-user” account with an award (store credit, which all referalls will get) This isnt expected behaviour – its not a coupon from your plugin, and the super-user account is no longer enrolled (I added it for testing, and it has been removed for a little while)

In this case, its no biggy, as I just wont use that credit (or delete it somehow) – but do you know why this happened, and will it happen everytime a non-CA coupon is used?

best wishes

Andrew
