Beacon show it's present or ranging even if, Beacon Battery is removed, what to do, to remove this bug?

问题

For StartMonitoring iBeacon my code is

-(void)startMonitoringForRegionWithUUID:(NSString*)UUID
{
    CLBeaconRegion *beaconRegion= [[CLBeaconRegion alloc] initWithProximityUUID:[[NSUUID alloc] initWithUUIDString:UUID] identifier:UUID];
    beaconRegion.notifyOnEntry = YES;
    beaconRegion.notifyOnExit = YES;
    beaconRegion.notifyEntryStateOnDisplay=YES;
    //[self stopMonitoringForRegionWithUUID:UUID];
    [self.locationManager startUpdatingLocation];
    [self.locationManager startMonitoringForRegion:beaconRegion];
    [self.locationManager startRangingBeaconsInRegion:beaconRegion];
}

-(void)locationManager:(CLLocationManager *)manager didRangeBeacons:(NSArray *)beacons inRegion:(CLBeaconRegion *)region
{
   NSLog(@"Number Of Beacons=%d",beacons.count); // show count for removed cell beacon too. there is no any other beacon with same UUID.
}

Above mentioned delegate methods show, false beacon. Even if, beacon battery is removed from beacon. Beacons array having present of those beacon. It happens when I run iPhone or iPad for almost 4-5 hours in beacon region. After restarting device,when didRangeBeacon callback happens it works fine. My question is, Why restarting does wonder? And what to do so I can avoid getting wrong beacon in callback method didRangeBeacons?

Note:- i am using Kontak iBeacon.
