Number of votes cast is the page title?!

Odd problem. On my site I have just noticed that the page title (shown in browser tab and source code) is the number of votes cast. So for example here:

The page title is “0” which is the same as the votes cast. If you vote for that post and refresh – the page title changes as well!

This can’t be good for SEO – whats wrong and how can I fix it please?
