Views in the database

Since the last database update something has been changed in the views within the database.
Earlier I had a report in which I selected some fields from view_invoices, this worked perfect. Now the select for the specific fields is overruled and all fields are shown. What has been changed?
For example:

select code

from view_invoices

In the SQL viewer it reports the codes (patients) and in a report it reports all fields now.
