Redwood How to remove the 'Source Assignment Status' field from Redwood 'Add Assignment'

Summary:

Within Redwood 'Add Assignment' 'When and Why' screen we have a new additional field 'Source Assignment Status' appearing when we choose 'Temporary' in the 'Will the assignment be temporary or permanent?' field (if we choose Permanent the field does not appear) and makes the 'What's the way to add the assignment' Required/mandatory but shows no values in the field. This is not a field we have in our current configuration (e.g. regardless of whether Temporary or Permanent is chosen it does not appear). Does anyone know how to amend the configuration to hide this field?
