Tracking number does not appear in eBay orders

from your last update when I insert a tracking code in GS (order section) and mark the item as shipped the code does not appear in eBay (status is shipped but does not show any code). If the shipping does not have a tracking code and I mark item as shipped in GS, in orders section of “My eBay” status does not change and it is still not shipped…

Hope you could repair it. Thank you
