The same values ​​in the quantity column after adding products again

During exploratory tests, I noticed that the fields in the value column are filled after adding the products again.

Reproduction steps:

1. Log into the application as administrator.

2. Go to Administration > Products and click the "View" button next to any product.

3. Click the "Create Kit Unpack List" and add some products.

4. Fill in the "Quantity" column and save the kit unpack list.

5. Click the "View" button next to the same Product and remove several products from the unpack kit list.

6. Click the "Add" button and add the products you just removed.

7. The added products already have the "Quantity" column filled.

Expected results:

• The column should not be filled in automatically.

Note: Also, without saving the kit unpack list, when you add products again, they have a filled column "Quantity".
