Adding Copied MED To Registry Fails And Modifies Original MED

Selected a MED from the registry and copied. Modified the new MED so that it will not have any validation errors. So it has its own unique namespace prefix and URI. When I try to add this new MED to the registry, I get an error saying that the MED already exists in the registry. If I close and reopen the MED registry, the original MED that I copied now has its namespace prefix and URI changed to the new MEDs values.
