Kotlin test method says "not called" and then says that it is

Im trying to have a base class with a base traveler but when I try to test if the function form that base traveler was called it says that is not and then it says that there is!

open class BasePresenter<V : BaseView, T : BaseTraveler>() {
  var view: V? = null
  var traveler: T? = null
  var userRepository: UserRepository? = null
  val compositeSubscription = CompositeSubscription()

  @CallSuper
  open fun onCreate(view: V, traveler: T, userRepository: UserRepository) {
    this.view = view
    this.traveler = traveler
    this.userRepository = userRepository
  }

  //...
}

class LoginPresenter : BasePresenter<LoginView, LoginTraveler>() {
  override fun onCreate(view: LoginView, traveler: LoginTraveler, userRepository: UserRepository) {
    super.onCreate(view, traveler, userRepository)
    view.initViews()
  }

  fun onButtonLoginClick(username: String?, pwd: String?) {
    if (fieldsAreInvalid(username, pwd)) {
      return
    }

    view?.showProgressDialog()
    userRepository?.login(username!!, pwd!!)
        ?.compose(Transformations.applyIoSchedulers<Session>())
        ?.subscribe({
          view?.dismissLastProgressDialog()
          traveler?.startLoggedViewWithCleanStack()
        }, {
          view?.dismissLastProgressDialog()
          manageError(it, false)
        })
        ?.followLifeCycle(this)
  }
}

Test:

class LoginPresenterTest {
    @Mock lateinit var view: LoginView
    @Mock lateinit var traveler: LoginTraveler
    @Mock lateinit var userRepository: UserRepository
    lateinit var presenter: LoginPresenter

    @Before
    fun setUp() {
        MockitoAnnotations.initMocks(this)
        mockSchedulers()

        presenter = LoginPresenter()
        presenter.onCreate(view, traveler, userRepository)
        reset(view)
    }

    @Test
    fun test_onButtonLoginClick_ifSuccess_startMainView() {
        val session = MockSession.session()

        `when`(userRepository.login("clark", "123")).thenReturn(just(session))

        presenter.onButtonLoginClick("clark", "123")

        verify(view).showProgressDialog()
        verify(view).dismissLastProgressDialog()
        verify(traveler).startLoginViewWithCleanStack()
    }   
}

But I get Error:

Wanted but not invoked: traveler.startLoginViewWithCleanStack(); -> at LoginPresenterTest.test_onButtonLoginClick_ifSuccess_startMainView(LoginPresenterTest.kt:57)

However, there were other interactions with this mock: traveler.startLoggedViewWithCleanStack();

Why? Is it an inheritance problem?
