The desciption meta tag is not showing in a Google

I have realised the desciption meta tag is not showing in a Google organic listing on a new site.

Please see below the meta tags. I have always used these tags before without a problem. I have double checked the code and researched the correct syntax but can't see what is wrong. I also used a spider simulator at Webconfes and it saw the description tag.

Google Search only shows the meta-description if it thinks it’s useful in that context (which might depend on various factors like query, user, previous searches etc.).

From Google’s documentation Review your page titles and snippets (bold emphasis mine):

Google will sometimes use the meta description of a page in search results snippets, if we think it gives users a more accurate description than would be possible purely from the on-page content.
