Open a project created on QDS 4.5.1 QDS451.zip

There is a component named ColorizeEffect under BorderItem:

    BorderItem {
        id: border1
        x: 260
        y: 285
        layer.enabled: true
        layer.effect: ColorizeEffect {
            id: colorize
        }
        adjustBorderRadius: true

But user cannot find this component on Navigator -view or in Components -view
