The bar considers amounts of products that have no shipping cost

Hello!! I would like to ask you for help. I noticed that when downloadable or bookable products that have no shipping cost are added to the shopping cart, the bar does consider them to calculate the amount remaining for free shipping. It would be great if the amount of those products were not considered.

Is there any way to achieve this? Thank you so much!
