addRecipient - duplicate chips

[azusdex]

Hi,
I added contacts with method addRecipient, and get duplicate chips.
Here my code:

activity.xml
<com.android.ex.chips.RecipientEditTextView android:id="@+id/phone_retv" android:layout_width="0dp" android:layout_weight="1" android:layout_height="wrap_content" android:textColor="@color/colorPrimary" android:fontFamily="@font/montserrat" android:minHeight="58dp" />

on Activity.kt

    lateinit var numbersTo: RecipientEditTextView

    override fun onCreate(savedInstanceState: Bundle?) {
        ...

        numbersTo = findViewById(R.id.phone_retv)
        numbersTo.maxChips = 10
        numbersTo.setTokenizer(MultiAutoCompleteTextView.CommaTokenizer())
        val adapterRecipientEditTextView = 
            BaseRecipientAdapter(BaseRecipientAdapter.QUERY_TYPE_PHONE, this)
        adapterRecipientEditTextView.isShowMobileOnly = true
        numbersTo.setAdapter(adapterRecipientEditTextView)
   }

  override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
        super.onActivityResult(requestCode, resultCode, data)
      ...

       val entry = RecipientEntry.constructGeneratedEntry(displayName, mainNumber, true)
       numbersTo.addRecipient(entry)
  }

this a result:
