Unclosed tags

Hi, I’ve been using your plugin for some time with LayersWP builder with good effects, but recently I noticed in fac widgets unopened p and a tags.

Example:

<div id="fac_promotion-12" class="widget widget_fac_promotion">
<div id="fac-fac_promotion--1" class="fac-promotion-main-section" style="color: #ffffff!important">
        <a href="http://jj.art.pl/articles/" title="" target="_self" style="color: #ffffff!important"></p>
<div class="fac-promotion-preview">
<div class="fpp-inner">
<i class="fa fa-file-text-o"></i></p></div>
</p></div>
<div class="fac-promotion-content" style="display: none;">
<div class="fpp-inner">
<p class="fac-description">ARTICLES</p>
</p></div>
</p></div>
<p>        </a>
    </div>
</div>

The same on other widgets.

Any ideas what is wrong?
