Extra fields in Redwood Personal Fields - How to remove

Summary:

In the Redwood, Personal details page for the employee there appears to be around 15 extra fields that have been added.
Once such field is 'NINO Verified'

Some other fields we are able to use VBS and find them via the search option, and then see if they can be hidden/made visible etc.
Others we can find them and it will state they are 'Default' rules therefore can not be changed.

However for the new fields in Personal details, although they are showing on the system/VBS Preview, we can not find the rules for them to see if they can be hidden.
