Sales Order Detail Attachment Duplicated.

When we enter a Sales Order Detail Lines through Import from Excel, after Import Completes the Order Lines Detail Attachment are Duplicating with the Recent Attachment Values.

After Importing the Sales Order Detail Lines from Excel, example 40 Lines

Next I add an attachment to Line Number 1. Example "Test 01"

Then when we are trying to add Attachment for Line Number 2 the Attachment from Line Number 1 gets Copied to Line Number 2 and so on.

If we are changing the Text in the Attachment from "Test 01" to "Test 02xxxxx" then after saving the attachment in the Line Number 2 it gets copied to Line Number 1.
