Since USPS CASS correctly autocorrects the address to 2 Nina Ct, validationGranularity set to PREMISE makes sense. However, the addressComponents fields are set to the original incorrect values, when I would expect them to be set to the corrected address. This behavior does not occur with some other addresses - e.g. "775 kimberly dr, gaithersburg, MD, 20878" corrects to "775 Kimberly Court East" in addressComponents as expected.
