Did you add the loopback after starting the routing process? The router-id is chosen at the time of the initialization.
Try "clear ip ospf proc" followed by a "yes". Then, "sh ip ospf". Or, reload the router. If that doesn't work, give us the output of "sh run | s ospf" so we can verify you didn't manually state a router-id.
