When viewing the relationship view of a User in CMDB, I have found that some of my Users have duplicate CI's for Monitors.  This must have happened when importing monitor assets.

When viewing the ALL CIs under CMDB, or in the User Relationship view, I can see the duplicate entries.  However when I select the Monitor category from the CMDB view, I only see the single entries for each monitor CI.  Please refer to the attached picture for a view of the duplicates.

Does anyone have a method to delete these duplicate CI's?
