Coupon code type incorrect workflow
https://demos.subrion.org/coupons/coupon/subrion-org/10-OFF-any-purchase/134.html
It's a basic coupon code. There should not be any view page for this type of coupon. Anyhow, when you edit this coupon on frontend and save it, you're redirected to view page. You should be redirected to category page / anchored to this coupon code.
Thanks
