Conflict with additional properties and internal fields

[leplatrem]

When editing an existing record, we get the following errors:

['schema'] is an invalid additional property
['id'] is an invalid additional property
['last_modified'] is an invalid additional property

The schema does not mention any of these...

I am now getting the following error when trying to edit an existing block:

Invalid root object field configuration:uiSchema order list does not contain properties 'schema', 'id', 'last_modified'.
