found some issues

I use the latest packs from https://github.com/greensock/GreenSock-JS to update my projects, and found some animation works weird.
likes below:

    <div class="row">
        <div class="col-xs-6" style="padding-right: 7px"
             data-animate-scroll='{"x": "0","y": "300", "alpha": "0", "duration": "0.5"}'>
            <img src="http://placehold.it/440x250" class="img-responsive img-rounded"/>
        </div>
        <div class="col-xs-6" style="padding-left: 7px"
             data-animate-scroll='{"x": "0","y": "300", "alpha": "0", "duration": "0.5"}'>
            <img src="http://placehold.it/440x250" class="img-responsive img-rounded"/>
        </div>
    </div>

the images will disappear after animation.
