S/o and quote history tracking wrong

Hello,

We have noticed on a hand full of Sales Orders that we pull up in Sales Orders and Quote history when we go to Invoices and check the tracking information it is incorrect and sent to the wrong address. However when I go to the shipping website such as FEDEX and use the same tracking number that was in Sage it pulls up the correct address of customer it was delivered to.

The kicker is all the other S/O's viewed tracking address have the same wrong shipping address.. all shipped by DHL to a London address.. 

Thanks for any help..
