I can't think of what the problem might be, unless you are handling the bread too much. Flour the tea towel well. Make sure you don't use terry cloth towels. Flour your hands and touch the dough quickly to form the loaf, it's good if the loaf is coated with flour on the outside.
If that isn't working then try changing the flour. Maybe the protein content is higher is some flours than others. I am more inclined to think it is one of the above problems. Lehi Roller Mills should be great flour! The recipe just calls for all-purpose flour.
Wish I was there to help you, but I am sure you will master this problem. Let me know how it goes for you.
