“Get the Cheapest Product for Free” not working when same product in cart

Hi,

We are trying to create a campaign where you get the cheapest item in the cart for free if you buy 3 product from the same Category (Bath towels).

If we for example add three products of the exact same variation, the campgin calculates correct at first then in checkout it adds an extra discount. It removes an extra 33%.

Ex. I add 3 of the Bath Towels for 50€, the total cart amount should be 150 € (but one should be free), so it should be 100€.

But it doesn’t work, it shows 66 €.

Is this a bug?
