xamarin - iBeacon ranging, Android, Minor always the same -

i've made app android detects ibeacons. it's based on 'find monkey example uses ibeacon library radius networks.

the app has been working fine until morning when started recognise 1 of beacons (i have maybe 6 in office).

the code loops through familiar have played ibeacons:

void rangingbeaconsinregion(object sender, rangeeventargs e)         {             if (e.beacons.count > 0)             {                 var beacon = e.beacons.firstordefault();                  var minor = beacon.minor;                  console.writeline ("minor .... " + minor);                   switch((proximitytype)beacon.proximity)                 {                 case proximitytype.immediate:                     console.writeline ("beacon fired minor " + minor);                     showcouponmessage();                     break;                 case proximitytype.near:                     updatedisplay ("you're getting warmer (near)", color.lawngreen);                      break;                 case proximitytype.far:                     updatedisplay("no beacons here (far)!!", color.blue);                     break;                 case proximitytype.unknown:                     updatedisplay("i'm not sure how close beacon (unknown)", color.red);                     break;                 } 

when stopped working, added console.writeline statement try understand beacon picking , why wasn't seeing others. looking @ console window, appears in fact 'see' other beacon's major , minor ids, chooses identify beacon minor of '2'.

here's section of output window:

as can see, 'see' beacons other minors, seems want identify 1 beacon have minor of '2' , continually outputs console window.

any ideas happening here? android bluetooth stack bug? i'm running android 4.4.4 on nexus 4, , thought bug resolved in 4.4.
