How can I add a user to the free version if I cannot add a role

I am trying to add a second user to the free version and it asks for a role.  According to the FAQ, that should show up in Users & Permissions but it does not.  In addition, I cannot even use a set role (CEO) as they do not show up and I cannot type into the Role field.
