Removing Workstations from Server Audit in AD Audit Plus

Removing Workstations from Server Audit in AD Audit Plus

I just installed Log360 and it populated my workstations automatically. But it pulled a bunch of old disabled workstations from my Active Directoy. I and goto Server Audit and then Configured Servers and Clcik Workstations. Here I try to delete any workstaton but get the error that says Sync servers can not be deleted.
