Ad not showing properly with advancedads or wp quads

Hi

I am trying to introduce the shortcode using some ad management plugins: advancedads or wp quads. I am trying a firt ad placement before content with a table 1×1 created with the plugin. I use the table as a call to action.

The problem is that it does not display properly. The table shows but broken.

If I place the shortcode in a single post it works though.

What could be the problem?

Thanks
