FrontMatter not fully "extracted" when used in the blog module

I hope the title makes sense as the question.

I’ve been creating a blog, and my articles frontMatter contains several fields like
date: xxxxxx
cssLayout: blog
category: xxxx
title: “xxx xxx xxx xxxx”
description: “xxx. …”
keywords: ‘xxx, xxx, xxx’
author: Andrea
SearchFromSummary: true

However, when I do try to retrieve the FrontMatter data with the blog.articles[0].data I got just some of them (always the same).
I can’t figure out what’s the issue here. Any help?

Also, can somebody remember me what the page_articles is. I assume it is an helper method, but I was not able to read anything on the help pages.

Thanks

Ok. By updating to the most recent version solved the issue. Didn’t realise a new push was available.
