I am creating a new group to restrict user access in the accounting application, however when those users try to modify fields in the product template referring to the UNSPSC code of the accounting section they do not appear.

The only restriction of this section is in the accounting tab that is only shown to users of the billing group, I already added my new group and the tab appears but without showing the fields it contains (The fields have no apparent restriction)

Another thing that I tried was to duplicate the billing group and add my test user to the group but it is still the same case, it only shows me the tab but not the fields.

i appreciate the help.
