Despite my refund for user Final9876 being a full refund, I cannot delete the subscriptions from user management, because when I check the delete checkbox the message "Product instance still has children and can not be deleted" is displayed.
As I tried to explain, the user (Final9876 - I PM-ed his username and password) had 3 subscriptions - one parent and two children - but only the parent is now displayed. So although I would like to delete the two child subscriptions first (1st Family Member and 2nd Family Member) I am not presented with the delete option.
