Entering tracking number & marking posted not saving

Hi Guys



Has anyone else has any issues with marking items as posted, yet they still remain in the sold view, awaiting shipping?



I have been entering the tracking number, which usually saves with the tracking number there to see and the posted icon filled, but it's not happening. So I am packing items, entering the tracking number and saving all the info - then go to the sold list - there it is, like I haven't done a thing!



Worry is that I could send this item 10 times, if I don't take the time to really think about what I am doing.



Thanks
