What is the version of SEP you have?

I had seen this issue in the earlier version of SEP, make sure you are on RU6 and above

These Duplicate entries are they in User Mode or in Computer Mode?

Have you done AD Sync?

Does the Duplicate Entry also show Green Dot?

Are these machine installed of a drive image?
