We're setting up some extended promotions rules. 
In this case i want to simplify things for our staff.

 

Let's create a promotion for Cyber Monday, the problems start when excluding products.

I make a new cart promotion called Cyber Monday 2019.
The bonus is simple: Order discount -> To percentage of original price 79 (to give a 21% discount)

 

This simply goes for all products except for two specific brand (which isn't allowing discounts)

If any of these conditons are true:

Condition1 -> Brands

Is not in -> Brand a

Condition2 -> Brands

Is not in -> Brand B

 

This works, when adding any product it gives a 21% discount, except on products from brand A or B.

Now it starts:
When adding a discounted product AND a product from brand A or B, the discount will be on BOTH products, including the one from BRAND A or B
What am i doing wrong here?
