XCTU (6.1.2) rarely recognizes XBees with "End Device" Configuration. Anyone know something about this issue?

Hello everybody,

I have issue connection my XBees to XCTU (but only if the xbees have “End Devices” - firmare). The connection rarely succeeds.
If I set the module to “Coordinator” - firmware everything works fine.
