@fishsilver: Have you checked the applicable CSV file on your Star Seller page to confirm which order(s) Etsy thinks was shipped late and / or without verifiable tracking?
What happens if you click on the tracking number link on the actual order? If it opens the courier's tracking page and shows the scan history then you have proof that the tracking information was entered correctly. In that case you should pursue it - while Etsy will not manually adjust Star Seller stats they can, in some cases, fix the underlying data and then the Star Seller stats will auto update (but not retroactively).
If that does not work and if the shipping company is supported by Etsy make sure that the shipped date, tracking number and shipping company show correctly on the actual order. Etsy relies on a third party vendor for tracking (and tracking number validation) and uses the data on the order. An unsupported shipping company or invalid / unverified tracking number equals shipped without tracking.
