OPmanager 11 apps plugin, email server monitor

Hi, I create new monitor in apps-messaging system tab.
But I forgot to include this monitor to a group or to create a new one, so although it seems created but I could not find it.
Problem is the monitor for email server is creating testing email every 5 minutes and I would like to remove this setting.
Since I could not find the monitor that I create, i could not remove this and it keep spamming emails.
How can I remove the monitor that I create if I could not find it under any group ?
