Automatic Discount Not Subtracting from Cart Total

[xyz1123581321]

Description: When a discount is applied automatically to the cart, the discount amount is not subtracted from the total. This issue occurs when an automatic discount rule is triggered and applied without user input, but the cart total remains unchanged.

Steps to Reproduce:

Add items to the cart to meet the criteria for an automatic discount (e.g., spend threshold or specific item).
Proceed to view the cart.
Note that the discount appears as applied but the cart total remains the same as it was before the discount.
Expected Behavior: The cart total should reflect the discount amount by subtracting it from the subtotal.

Actual Behavior: The cart displays the discount, but the total does not decrease to reflect it.
