Need help showing coupon discount ammount in invoice and order details page

We are using Awocupon pro 3.6.0.3, Joomla 3.9.25 and virtuemart 3.8.8. with 

Clean mart template solution on this forum https://www.flexiblewebdesign.com/forum-joomla-virtuemart-template-sportmart-support/3171-coupon-code-weird-code-field-in-white#13465

We are using  20% discount code "JUNIJ20"  only active for this product https://ghee-kozmetika.si/bio-smilj-ali-immortelle-helichrysum-hranilno-vlazilna-krema-za-obraz-50ml

1.) When we select the product and enter the coupon code in step 4 and click "apply coupon button" first we recive message "coupon code not found" which is strange.. 

2.) But only after clicking on the payment option in step 5, the coupon values are shown, and order total value is deducted..

3.) But no cupon values in table row "popust" are shown in invoice and order details page.

How can we fix that?

We can supply backend login and ftp if needed.

Please help.

Best regards,

Rok

Hi, thank you very much. I looks like it is working ok.

Maybe you now where I can disable the table "POPUST" as it is showing 0 values in one column for order details?

Best regards,

Rok
