Description

When attempting to offer multiple child variants of a single configurable product as free gifts, we encounter an issue. For example, I created a configured product named "test-tshirt" with child variants like "test-tshirt-Black," "test-tshirt-Blue," and "test-tshirt-White." I then create a cart rule with specified conditions, intending to provide 1 quantity each of the mentioned SKUs (test-tshirt-Black, test-tshirt-Blue, test-tshirt-White) as gifts. However, only one SKU( test-tshirt-Black with 3 quantity) is being given as a gift

Steps to Reproduce

1: In a clean Magento shop ,installed the Magesuite-FreeGift module
2: Now From the admin side, create a configurable product with multiple color or size variants. For example, I have created a product called 'test-tshirt' as a configurable product and added variants such as 'test-tshirt-Black,' 'test-tshirt-Blue,' and 'test-tshirt-White.'
3: After,navigate to Marketing -> Cart Price Rules. Create a new cart rule, and within the Actions tab, set the options as depicted in the screenshot below

(Note: in gift sku’s add multiple child varients of same configurable product else you can not reproduce the issue )
4:Upon adding a product from either category 3 or 4 (Gear or Bag) from frontend, only one SKU (test-tshirt-Black) is provided as a free gift with a quantity of 3. The other SKUs, namely test-tshirt-Blue and test-tshirt-White, are not being given as free gifts. I have attached a screenshot for your reference to verify the issue.

Expected Result

All the sku’s that i add in gift sku’s should be given as gift

Actual Result

Only one product is given as gift when i add multiple child varient sku’s of one single configurable product
