When you export a default solution from one organization so that you can create a look-a-like in new out of the box organization not everything comes over. Sure we know that users will need the security roles assigned,etc. But this caught me by surprise the other day, I now have it added to our check list. You will need to assign users to the their specific Field Level Security for the fields that they control. Otherwise no one except CRM Admins will be able to see those fields.
