Problem with scrolling when using Wowjs JQuery plugin

I used Wow.js plugin for animations when scrolling but i had a problem that occurs on mobile phones, when you reach Pricings section you'll be unable to scroll for some reason.. I'm using bootstrap 3 by the way

I've tried to change the animation effect but still makes no sense, so i guess it's not from the animation

<div class='plan col-md-4 wow bounceInUp'>
                    <div>
                        <div class='head'>
                            Basic
                        </div>
                        <div class='price'>
                            <p><span>$</span>0</p>
                        </div>
                        <div class='offer'>
                            <p>Free for Life</p>
                        </div>
                        <ul class='list-unstyled'>
                            <li>1 GB of Space</li>
                            <li>10 GB of Bandwidth</li>
                            <li>3 Websites</li>
                            <li>Basic Customization</li>
                            <li>WordPress Integration</li>
                            <li>Email Support</li>
                        </ul>
                    </div>
                </div>

It should scroll normally but i don't really know what's wrong
