Symptoms:
TM entries using SID are duplicated when the target is changed or the status of the segment is changed.
Resolution:
You can fix this issue by deploying the update to WS 11.2.0, available on FTP.
If you cannot deploy it, connect to the Customer Support Web Portal and log a case. You need an account to log a case. If you do not have an account, contact your company's SDL Support Account Administrator.
