How to set product is tangible with free shipping - 2Checkout Parameter.

I am new 2checkout and sell product tangible all products are free shipping on my website.
I see sale transaction in my 2checkout show as "Intangible Sale No Shipping" when I made payment (test). The shipping address not show. This is my problem because I can not mark as shipped in 2Checkout. But when I set handling fees = 2, my sale transaction show up shipping address.
How to set my product tangible with free shipping?

Thank you.

Not sure why you're asking a question about 2checkout in the Zencart support forum?

They said in Zencart can change my product to tangible product, but I have no idea to solve :no:. And they suggest me to post in Zencart support forum.

Thank you.
