Section disappeared after upgrading from 4.5.7 to 4.5.14

I moved from Pro 4.5.7 to Pro 4.5.14 and the section below does not appear anymore:

<div class="view">
    <div class="full-bg-img">
        <div class="mask flex-center">
            <div class="container text-center">
                <div class="flex-center" style="height: 150px;">
                    <img class="logo_center_big animated bounce" src="img/samples/people_code_sample.png" alt="logo">
                </div>
                <div class="black-text text-center wow fadeInUp" style="font-size: xx-large;">
                    <div id="typed-strings">
                        <p><strong>Text message. Text message. Text message. Text message. Text message. Text message. Text message. Text message. Text message. Text message. Text message. 
                        </p>
                    </div>
                    <span id="typed"></span>
                </div>
            </div>
        </div>
    </div>
</div>


The whole section just doesn't show up on the web page anymore.

I think the culprit is the "full-bg-img". How do I make it compatible with the latest version?

Yup, I searched the mdb.css file and indeed the:

.view .full-bg-img,
.view .full-bg-img video {
  background-repeat: no-repeat;
  background-position: center center;
  -webkit-background-size: cover;
  background-size: cover; }

is missing. 

What is the equivalent way to do this in 4.5.14. Please help. Thanks!
