False zone Enter/Exit events in Background Mode with iOS Proximity SDK

We have built a demo app from your deskObserver example: https://github.com/Estimote/iOS-Proximity-SDK/blob/master/Examples/Swift/DeskObserver/DeskObserver/ViewController.swift

To be able to test how the app works in Background Mode we have added to it a remote tracking of zone Enter/Exit events (we send those events to Mixpanel server). In Foreground Mode the app works as expected, but when device goes into sleep mode the app starts acting strange: it starts endlessly firing same zone Enter/Exit events even though the device is laying still on a table and a beacon is laying on a sofa just 1.5 meters away. The beacon represents ‘Blueberry desk’ zone with 4 meters range.

Could you confirm that it’s a bug, or maybe I’m doing something wrong.
