About Bogo

Hi Im having a problem with Bogo offers.

I have a category which has 20 products in it. 19 of them has a campaings as;

Buy 10 Product A and up to 19 qty – Get 1 Product A Free
Buy 20 Product A and up to 29 qty – Get 3 Product A Free
Buy 30 product A and up to 49 qty – Get 5 Product A Free
And it goes like this and this will be same for another 19 different products in that category except 1 of them as I mentioned before.

When I make a rule for only the (buy 10 get 1) I make the rule as it is on first 2 pictures and result on the 3rd picture, it works.
1st Picture
2nd Picture
3rd Picture

But when I edit the rule as on 4th and 5th picture it stops working as you can see on 6th picture.
4th Picture
5th Picture
6th Picture
Where am I doing wrong? I know there is a small point Im doing wrong but where?

By the way Im using the free version.

Thank you

Emre
