Shortcodes not working

Hi there,

I have a number of plugins that create really handy shortcode snippets. However, when I paste the shortcodes onto a wp adverts post, they don’t work.

This is one of the plugins I’m talking about:

It creates a snippet that looks like this:

How can I get them to work in wp adverts posts?

Thank you.
