Shipping Coupon accepted but no discount applied

I am testing AwoCoupon Pro 2.5.8.2 with a Shipping Coupon.  I am using Joomla 3.7.4 with Hikashop 3.1.1

It is set up as follows:

Value - amount - $15
Minimum Value - $50 - overall
Valid from 8-18-17 to 31-8-17

Shipping
Includes all Shipping Methods for between $50 and $150

Order is for $85.

When I apply the Coupon code, it is accepted but only shows as $0.00.

Any advice appreciated.

Thanks in advance.

Thanks for the admin access.

I reproduced this on your site, but also I tested this locally trying to replicate all your settings and cannot.

Could you send temp ftp access to debug it?

Thanks for the access.

Found an issue with the way AwoCoupon was getting the shipping from Hikashop.  This has been fixed on your installation, and will be fixed on the next update.
