Klarna returns error when totalAmount differs from sum of orderLine when using discount (on the whole order instead of orderLine)

[frekel]

When we add a coupon for the complete order (thus giving a discount on the whole order), the totalAmount is not the same as the sum of the orderLines. Klarna then returns an error that the amount are not the same.

How can we fix this? (we can't add a new orderline with just the discount as Magento does not support this)

We did try to upgrade to the latest version (5.6.8) but that did not solve the problem on our acceptance environment.
