I have just tried a test listing using the original item as recorded above and have been unable to replicate the issue myself - whilst it could be easy to explain as a PEBKAC I list 600-900 items a month and adding additional postal services is something I have done thousands of times. Its possible its something I did but I would have to have had to overwrite fields which I had just filled in moments before for the additional services not to show up as intended.
