After changing the employee responsible, the other areas of the transaction is changed.. why?

Hi All,

Before editing, the details are as following screenshot in transaction.

The issue is, when we change the Processor (Employee Responsible(User)), the Asset Owner(Sold to party) and the shipping address in transaction are become empty fields, screenshot is attached below for your reference.

Could you please give me your inputs to fix this issue. 

Regards,

Maddy
