This is fixed in 19.2.7.0:
6523: Bug
Title: Amount discount is only applied once even if quantity is doubled or tripled
Description: Previously amount discounts did not stack with quantity, this has been fixed
This fix result in another problem: I use the discount to apply a negative discount to selected groups, for example “Tickets”: If one or more tickets are bought, then a discount of "-12" is applied. I call this discount “Shipping fee” and the client will only pay 12 dkk no matter how many tickets there are sold.
Can you make an option, so we can select if the discount should be applied only once (the ‘old’ method) or if the discount should be applied multi times (the ‘new’ method)?
