Hi Felipe,
it sounds a bit like you are trying to add roles in the database (the role table) and then hope they will show up as roles to be used in your code in Service Studio in that espace.
I don't think it works that way, I think adding roles in Service Studio, makes them available in the role table with the purpose of being able to authorize users for that role, but not the other way. Adding a record in that table will not magically make that role appear in the espace for coding.
