A Conflict with Customizr theme?

Hi,
recently I changed my WordPress theme to “Customizr”, after that Insert Pages plugin started to display some list tags on the page like;

<ul class='post-meta'>
<li><span class='post-meta-key'>tc-thumb-fld:</span> a:2:{s:9:"_thumb_id";i:1103;s:11:"_thumb_type";s:10:"attachment";}</li>
<li><span class='post-meta-key'>layout_key:</span> </li>
<li><span class='post-meta-key'>post_slider_check_key:</span> 0</li>
</ul>

What should I do to stop displaying these codes?

Sorry for my poor English, Thanks for reading.
