You have detections on your homepage by an unmanaged detector and after disabling the client as an unmanaged detector, the detections made by this client are still reported.
Symptoms
There are a number of potential causes for this issue. Changing the unmanaged detector's hostname, mac address, and various other network information may cause this issue.
If disabling the client as an unmanaged detector does not remove the detections, you can delete the client from your manager and any detections made by the client should be deleted.
