Product fields problem

wordpress 3.5.1 and Ready! Ecommerce Shopping Cart 0.3.2.3

after installing, I added 2 fields product (Html Type: text) applying to all categories and I saved. I noticed right away that going to modify the product parameter, the value type combo is empty.

Adding a new product, the extra section field is empty and I do not see the two new fields.

Thank you,
Regards
