Custom Post description getting replaced with post author

Hi,

I have a site using a classified theme which has its own custom post for the classifieds called Ads. After installing Yoast, I tried posting some of my classified Ads to Facebook. However when Facebook automatically loads the title, image and description from the Ad page URL, the description I see is wrong. Instead of taking the description from Ad page itself, it is taking the Classified Ad’s author name as the description.

I do not know if this will be the same case Google bot crawls my site. Will all my custom post page’s description be messed up? Or is this on Facebook alone? If it is only on Facebook, why could it be. This only happened after installing Yoast SEO.

I dont have any other SEO plugins installed, in case you might be wondering.

Below is one URL which you can test on facebook. The moment you put the URL it should load the content of the page. So you can see the author name is coming instead of the actual description. (Pls join the URL to correct it. I have put some spaces to make it not link)
