WordPress+Visual Composer losing settings.

Guys,

I build a new blog page using Visual Composer with Fortuna Headings and a Post Grid and, in Fortuna Page Settings: Show Page Heading OFF, Page Content Top Margin OFF and Activate Transparent Header ON (and Visual Composer with similar settings to the “Blog Masonry Grid” Page from Fortuna Theme Examples).

After a few minutes, the page has lost all settings! Using the settings above, the result of the page is http://teknosystem.com.br/blog/

What should I do? Could you help me?

This is a new website with WordPress 4.3.1 and all plug-ins updated.

Thanks!

Waldemiro
