This property is calculated based on the current barcode data. Depending on the barcode type, this property may contain additional check characaters and/or may have dropped non-ASCII characters there were present in the data; Code 39 barcodes may add a * to the beginning and end of the barcode data to form the caption.
For the barcode types we support, the default caption of the add-on portion (if any) of a barcode is the same as the barcode AddOnData. So there's no such a property called DefaultAddOnCaption.
