Enabling Free Shipping for all except weight >= 35lbs

Enable Free Options Shipping
True

Shipping Cost
0.00

Handling Fee
0

Total >=
0.00

Total <=

Weight >=

Weight <=
40.00

Item Count >=

Item Count <=
1

Tax Class
Taxable Goods

Tax Basis
Shipping

Shipping Zone
48 Lower States

Sort Order
0

So, instead of working as expected is not doing anything, I had Always Free Shipping enabled before, but I set it up to FALSE, even as that the products are not following my new rule ...
FREE SHIPPING

Enable Free Shipping
False

Free Shipping Cost
0.00

Handling Fee
0

Tax Class
Taxable Goods

Shipping Zone
48 Lower States

Sort Order
0
