YOAST SEO meta not showing in google (headway themes)

My site https://superphallic.com is using headwaythemes for design and I have installed Yoast’s SEO plugin.

I have entered the description I want to appear for meta (google results) but it is showing latest post titles and descriptions, comment counts and such.

In the seo>home section I have entered

Title template: %%sitename%% SuperPhallic
Meta description template: The weirdest drawings you will ever see.

I have given this info just in case you need it. I am using headway because I am no good with CSS or HTML or php so if you can see the problem please let me know where I can find it, exactly how to edit it if that is ok. Headway also has disabled it’s own seo as it recognised Yoast’s plugin.

Thank you
