How do I delete the original tracking number?  because we want changed tracking number ..wrong tracking number put ..how can we add new tracking number when we update new tracking number and  click save button.then again old tracking number appear.

You can't. The new tracking number should be added to the transaction, and both will remain.

(your post is unclear about whether you are having trouble entering the new tracking number, or if the problem is just that the old one won't go away)
