Ahh, I found the casuse of my problem now. Are you using http://schema.org/Person markup for the author box in your posts?
I thought I was doing it by the book by structuring all the data in correct schema.org tags, but it took over the entire page title on Google+
In my case I just replaced:
<div itemscope itemtype="http://schema.org/Person">
with:
<div>
Just noticed the same thing. Never seen it happen before.
Answering my own question here.. Add the following code to functions.php in order to show a meta box with categories. The category ID is stored as a custom field.
