No suitable style tag …

Hi

After I select a style for of my contact forms, no style is applied on that page.
I inspected the <form> element and I saw that the proper CSS classes are not attached to the tag.
<form class=”wpcf7-form cf7-style contact-form-1-2” novalidate=”novalidate” method=”post” action=”/contact/#wpcf7-f17-o1″>

Can you please check this?
