Widget content affected by emphasis tag

Hello again,

Other situation with the theme Just Landing Page Pro that I am “suffering” is that a strange tag is affecting two widgets and all the content inside (header and body text) is displaying with the em tag.

I paste the code:

<div class="block3-center3">
<div class="sidebar-user14 span2">
<div class="sidebar-user15 span2">
<ul>
<li id="text-38" class="widget widget_text">
<em>
<li id="text-48" class="widget widget_text">
<h2 class="widgettitle">LOREM IPSUM</h2>
<div class="textwidget">
</li>
<li id="text-39" class="widget widget_text">
</em>
</ul>
</div>
<em> </em>
</div>
<em>
</div>
<em> </em>
</div>
<em>
<div class="block4">
<div class="block5">
<script src="http://www.xxxxxxxxxxxxxxxxxxxxxx.com/wp-includes/js/admin-bar.min.js?ver=4.0" type="text/javascript">
<script src="http://www.xxxxxxxxxxxxxxxxxxxxxxxx.com/wp-content/plugins/contact-form-7/includes/js/jquery.form.min.js?ver=3.51.0-2014.06.20" type="text/javascript">
<script type="text/javascript">
<script src="http://www.xxxxxxxxxxxxxxxxxxxxxxxx/wp-content/plugins/contact-form-7/includes/js/scripts.js?ver=3.9.3" type="text/javascript">
<script type="text/javascript">
<div id="wpadminbar" class="" role="navigation">
</em>

I have searched the php files that I have found in the WordPress Editor without finding the tag. Also I have bean searching for it in de CSS stylesheet without being succesfull.

Again, thank you in advance!
