Ciscoworks Discovery - Multiple duplicate devices after each discovery

[jabeck018]

Most of our devices are currently in DNS and the hostname is resolving correctly. However, I am seeing multiple duplicates (around 200) on each discovery where the device is added with the IP Address as the hostname/display name. Shouldn't Common Services recognize these are duplicates based on IP Address?

Common Services 3.1.1
