Discounts/vouchers Not Being Calculated Correctly

[ChrisRabkin]

Hello All!

I have a client that sent me an image where it clearly shows 2 discounts in their customer's cart but the combined total of the vouchers are being shown differently in the cart total.

 

There is a referral reward of -5.00 and a voucher of -32.11 available but the total as shown in the attached image is -34.68.

 

This customer is part of a tax exempt group.

 

Does anyone have any notions of why this would be happening?

 

The current version of PrestaShop is 1.6.1.1

 

I am going to be updating php to the latest version today but I don't think this part of the issue.

 

Thanks for any help you can provide.

 

Chris
