[Plugin: WordPress SEO by Yoast] no description on Google Snippet

First of all, I think WordPress SEO by Yoast is easily the BEST SEO plugin ever.

I’m having an issue using WP SEO in my serp: in Google Snippet, description isn’t shown. Description is hidden for my homepage and for every page of my blog Ideageek.it. Look this screenshot: https://gyazo.com/5b7d8a96a99551144fbe85a9e424d3aa.png

I’m using the right setup, you can see meta tag description into HTML of every page of my blog https://ideageek.it

s there any way to fix it?
