QML SwipeView is covering entire window

I am having some problems if i use swipe view and i have written following code:

import QtQuick 2.6
import QtQuick.Window 2.2
import QtQuick.Controls 2.2

Window {
    visible: true
    width: 640
    height: 480
    title: qsTr("Swipe View")

    MainForm {
        anchors.fill:parent

        Rectangle{
            id:rightRect
            anchors.right:parent.right
            width: parent.width*0.50
            height:parent.height
            color:"yellow"
        }

        Rectangle{
            id:leftRect
            width:parent.width*0.50
            height:parent.height
            color:"lightgreen"
            border.color:"red"
            anchors.right:rightRect.left
            SwipeView{
                id:swipeView
                anchors.fill : leftRect
                //Layout.fillWidth: true
                currentIndex: 0
                interactive: false
                Page{
                    id:page1

                    Rectangle{
                        width:parent.width
                        height:parent.height
                        color:"lightgreen"
                        Button{
                            text:"move to 2"
                            onClicked: swipeView.currentIndex = 1
                        }
                    }
                }

                Page{
                    id:page2
                    Rectangle{
                        width:parent.width
                        height:parent.height
                        color:"lightblue"
                        Button{
                            text:"move to 1"
                            onClicked: swipeView.currentIndex = 0
                        }
                    }
                }
            }
        }
    }
}

Below are the screen shots:

1) Initially i have set current index to "0" but index "1" blue area is visible and it's covering the right area(Yellow rectangle):

2) if I click on move to 2 button then the yellow rect is visible as expected.

Now, Even if I click on move to 1 button I need same behavior ie., yellow rect should be visible all the time.How to achieve this ??
