Editing overlay text

I am helping someone revise their website. There is some text overlaying the Meta Slider that we need to change, but I can’t find a setting that will let me update it. It’s under this code:

<div id="metaslider-id-453" style="width: 100%;" class="ml-slider-3-27-13 ml-slider-pro-2-18-8 metaslider metaslider-flex metaslider-453 ml-slider full-width nav-hidden">
    <div id="metaslider_container_453">
        <div id="metaslider_453" class="flexslider">
            <ul aria-live="polite" class="slides">
<li style="display: block; width: 100%; float: left; margin-right: -100%; position: relative; opacity: 1; z-index: 2;" class="slide-549 ms-image flex-active-slide"><img src="https://-------.com/wp-content/uploads/2017/07/sunset-ocean-hero-1440x600.jpg" height="600" width="1440" alt="" /><div class="caption-wrap"><div class="caption"><img src="/wp-content/uploads/2017/07/hero-signature.png" />
<h3 class="hidden-xs">THIS IS THE TEXT I NEED TO CHANGE</h3></div></div></li>

I do see that this client has Meta Slider Pro installed, but I’m sure the support has expired. Do we need to reinstate Pro to update this text?

It works with other themes: Haven’t Tried
It works when I disable all other plugins: Haven’t Tried
Meta Slider Pro version: 2.18.8
Meta Slider version: 3.27.13
