Configured on my site but does not appear to table

Hello
Installed and configured all the plugin, I requested to appear below the add to cart button, plots total, minimum and all functions.
Not appeared. Tested elsewhere in the product as tables or bottom of the page, and yet nothing appears.
Any suggestions of what can be happening?
Wordpress 3.5.1 + 1.6.6 Woocommerce

Site: loja.laborconcursos.com.br

Thank you!
