After DLP has been upgraded to 16.0 which includes a refreshed, more modern user interface, some users are seeing the older interface in their daily work.
If a bookmark using a 15.x URL is used, the old UI is used to render the page.
Update any 15.x bookmarks to 16.0 by navigating to the proper page within the UI, such as a saved report.
Example:
New UI: HTTPS://<ENFORCE>/ProtectManager/enforce/ui/incident/lists/101
Old UI: HTTPS://<ENFORCE>/ProtectManager/GetReport.do?reportID=101
