To start with pick up a single prefix may be a /32 and do a show ip route to it or look it up in the database to see which router is originating it. Apply the distance command on the basis of the router-id of the originating router ... it should work. To further confirm my understanding, I digged up and found this link: https://learningnetwork.cisco.com/thread/34133 It could be a bug. Regards, Samir Idris.
