Order net value and discount not displayed

Hi,
When using discounts, they are added to the order listing in hikashop.
In the related order in hikamarket, they are not displayed !

Here 2 screenshots. Orders from Hikashop => correct with correct discounts
Hikashop Order:

Related order object from hikamarket is not correct. Fee for vendor is correct, but the discount is not listed in the GUI and the net value is the wrong one. This causes problem for the vendor, because he will not see the dicounted value.

Related Hikamarket order for the order above:

I used AwoCoupon Pro for this.
In Hikashop it seems to work, because there is this option "Discount Target Vendor".

I guess, I have to contact AWOCOUPON people.

What do they need to set in the order object to discount also the vendor ?
Can you provide this info ? Then I will forward it.

Thanks and br
