peripheral.name vs. localName?

My app uses both the peripheral.name AND the advertisementData[CBAdvertisementDataLocalNameKey].  But every time I update advertisementData[CBAdvertisementDataLocalNameKey] by means of the CyBle_GapSetLocalName(), the peripheral.name value takes on the old value of advertisementData[CBAdvertisementDataLocalNameKey].  Is there anyway to stabilize the peripheral.name value so that it never changes from the initial value given when the 4200BLE is initially programmed?

Thanks.
