Delete Performance Monitor and/or Vendor

Delete Performance Monitor and/or Vendor

Hi there,

OpManager Build 11400

How in the world I delete a custom/vendor performance monitor?
I've added a new device/vendor and got the OID wrong by mistake.
I've deleted the Device Template, but the monitor still there, viewable in:
Settings > Configuration > Monitors > Performance Monitor

So i thought of getting rid of the new Vendor I've created .... but no such option.

Any help will be appreciated.
