Standard coupon dash visible for everyone

Hello, i tried to search but didn’t find this reported and not sure this is supposed to happen.

I realized that the coupon dashboard for non-plugin coupons (so unassigned to an user) is visible for everyone
Url example:
https://example.com/affiliates/?couponid=TEST

Anyone, even logged out can see this page and how many orders have been made with this coupon.
I did some research and found out the culprit in file woo-coupon-usage/inc/functions/functions-shortcode.php
at line 132

this check ($couponuser == $currentuserid)
returns true as coupon user is null and current user id is 0

Hope the staff can look into it
Thanks
