Hello,
You must write shorter meta titles.
You have 97 characters in your meta title - try reducing it at a maximum of 70.
When your title tag is too long, instead of simply truncating it and adding an ellipsis to the end the way they used to, Google is trying to algorithmically determine a better title for the post.
These are the algorithmic changes Google made in May, 2012:
- "Trigger alt title when HTML title is truncated. [launch codename "tomwaits", project codename "Snippets"] We have algorithms designed to present the best possible result titles. This change will show a more succinct title for results where the current title is so long that it gets truncated. We'll only do this when the new, shorter title is just as accurate as the old one."
- "Efficiency improvements in alternative title generation. [launch codename "TopOfTheRock", project codename "Snippets"] With this change we've improved the efficiency of title generation systems, leading to significant savings in cpu usage and a more focused set of titles actually shown in search results."
- "Better demotion of boilerplate anchors in alternate title generation. [launch codename "otisredding", project codename "Snippets"] When presenting titles in search results, we want to avoid boilerplate copy that doesn't describe the page accurately, such as "Go Back." This change helps improve titles by avoiding these less useful bits of text."

Regarding your cache version - Google will index your website faster when it has a bigger authority (popularity - build more valuable external links). It's only normal for your website to be indexed at a lower rate at this point.
