Open the URL in your management server.
You should see two folders in here
If you only have one then this is what is most likely causing the lack of endpoint updates. To resolve this if you Stop and disable the Data Security Batch Server service from services.msc and then go to the folder
C:\Program Files (x86)\Websense\Data Security\Data-Batch-Server\service-container\container\work
and move all of the folders in here to a new folder.
Now re-start the data batch service back up again. Then you need to give it a few minutes and then re-check the URL
and check now if you have the META-INF and WEB-INF in here.
If so then check now to see if you see endpoints now showing as updated
