Widget only showing Popular and disappearing Numbers

I love the concept of this plugin.

However on my site, I am only showing the Popular tab. Further code inspection shows that the Comments and third tab are right below the Popular Tab, so I am thinking ti is a CSS issue, possibly to do with alignment.

And another note is that the counts disappear after I switch tabs to week or month or day, and only come back when I refresh the page.
