JaVers - сравнивать сложные объекты, используя LEVENSHTEIN_DISTANCE с помощью custompropertycomparator

Я пытаюсь проверять объекты в списке, используя алгоритм LEVENSHTEIN_DISTANCE, регистрируя CustomPropertyComparator и registerValue. 

JaversBuilder.javers()
    .registerCustomType(Device::class.java, DeviceComparator())
    .registerValue(Device::class.java)
    .withListCompareAlgorithm(ListCompareAlgorithm.LEVENSHTEIN_DISTANCE)
                .build()

У меня есть сценарий ios, упомянутый ниже 

        var device1 = Device("d1", "device1") 
        var device2 = Device("d2", "device2") 
        var devices = mutableListOf<Device>()
        devices.add(device1)
        devices.add(device2)


        val before = Node("n1", "node1", devices)

        //1. Remove device2

        val newDevice1 = Device("d1", "device1")
        val newDevices = mutableListOf<Device>()
        newDevices.add(newDevice1)
        var after = Node("n1", "node1", newDevices)

        var diff = javers.compare(before, after)
        println("removed $diff")


        //2. Add device2

        device1 = Device("d1", "device1") // devices/d1 -
        device2 = Device("d2", "device2")  // devices/2
        devices = mutableListOf<Device>()
        devices.add(device1)
        devices.add(device2)

        val after1 = Node("n1", "node1", devices)

        diff = javers.compare(after, after1)
        println("added $diff")


        //3. Remove device1 from the device list

        device2 = Device("d2", "device2")  // devices/2
        var newDevices2 = mutableListOf<Device>()
        newDevices2.add(device2)

        val after2 = Node("n1", "node1", newDevices2)

        diff = javers.compare(after1, after2)
        println("removed device1 from the device list $diff")

Программа выше дает следующий вывод: 

removed Diff:
changes on com.example.audit.Node/ :
  - 'devices' collection changes :
    1. 'Device(deviceCode=d2, name=device2)' removed

added Diff:
changes on com.example.audit.Node/ :
  - 'devices' collection changes :
    1. 'Device(deviceCode=d2, name=device2)' added

removed device1 from the device list Diff:
 changes on com.example.audit.Node/ :
  - 'devices' collection changes :
    0. 'Device(deviceCode=d1, name=device1)' removed

Я ожидаю вывод чего-то вроде JaVers PrettyPrint, который упоминается ниже: 

removed Diff:
* object removed: com.example.audit.Node/#devices/1
* changes on com.example.audit.Node/ :
  - 'devices' collection changes :
    1. 'com.example.audit.Node/#devices/1' removed

added Diff:
* new object: com.example.audit.Node/#devices/1
* changes on com.example.audit.Node/ :
  - 'devices' collection changes :
    1. 'com.example.audit.Node/#devices/1' added

removed device1 from the device list Diff:
* object removed: com.example.audit.Node/#devices/0
* changes on com.example.audit.Node/ :
  - 'devices' collection changes :
    0. 'com.example.audit.Node/#devices/0' removed

Какое изменение я должен сделать, чтобы получить ожидаемый результат?
