perch_item_odd

What am I doing wrong. My template has a line like this:

<div class="panel <perch:content id="perch_item_odd" /> panel--cols panel--faqs">

All works fine, but in the CMS an extra field is displayed:

<input type="text" id="perch_36_perch_item_odd" name="perch_36_perch_item_odd" value="" class="text ">

Can I get rid of that?
