There is a bug where applying a coupon triggers a conflict with a promotion associated with a utm_campaign. When a promotion is activated by a specific utm_campaign and a coupon (which also has its own utm_campaign configuration) is added, the coupon removes the initial promotion. Despite the initial utm_campaign remaining in the orderForm, the initial promotion is no longer applied. The second promotion is triggered by the coupon, not by the UTM.

To reproduce this behavior, follow these steps:

1. Create Promotions:

• First Promotion: Set up a promotion for free shipping that is triggered by a specific utm_campaign. This promotion should be configured to activate based on the UTM parameter without requiring a coupon.
• Second Promotion: Set up a promotion that provides a percentage discount and is associated with a different utm_campaign. This promotion should be configured to require a coupon for activation.

2. Reproduce the Bug:

3. Access the store using a link with the utm_campaign parameter that matches the first promotion (e.g., utm_campaign=FREE_SHIPPING).

4. Add products to the cart.

5. Enter a postal code in the cart.

6. Verify that the free shipping promotion (first promotion) is applied.

7. Apply a coupon that triggers the second promotion (e.g., DISCOUNT20).

8. Observe that the initial free shipping promotion is removed from the cart after applying the coupon, even though the initial utm_campaign remains in the orderForm.

If the second promotion (triggered by the coupon) is configured with a utm_source instead of utm_campaign, the bug can be circumvented. In this case, both promotions will be applied successfully without any conflict.
