Min-Max products doesnt work

Hi!

I just made my first bundle and I’d like my customers to choose if they want a pack of 2 ebooks, or 3 ebooks. So I set the limit whole items to min 2 max 3.
But if I want to order 2 ebooks and set 1 to quantity of 0, my cart still makes it a 1 and sets the discountprice for 3 ebooks.

How does it work if they want just 2 and the percentage discount is the same? Because it shows the right price at the product page.

Kind Regards
Mari?lle
