[Plugin: Front-end Editor] Tags not correctly closed

Activating the editor works in most parts of the website. But in some parts corrupted links occur…
<div class="folio-desc">
<h2><span data-post_id="119" data-type="inpu</h2>
<p class="excerpt"><div data-post_id="119" data-type="textarea" data-filter="the_excerpt" class="fee-field fee-clearfix">

I can send you through a PM the direkt link, where you can look at it…

Kindest regards.
