Once the service isn't visible anymore (eg. reboot), it will disappear from the GUI.

Before or after you disabled the service?
Alwin, I figured out how to get rid of the ghost monitor today...
Go to Shell on node with ghost monitor
ls /var/lib/ceph/mon #should see name of monitor
rm -rf /var/lib/ceph/mon/<name of monitor>

I then navigated to Ceph page in GUI and the ghost monitor was gone...
