[theme: Twenty Twelve] Two Nav-below

hello,
this is my site: https://norest4thecollectors.x10hosting.com/?paged=2

Scroll to the bottom and you notice two instances of Nav-below…. this appeared after the last 20-12 update… I found one instance of Nav-below in single.php as expected… I am unsure where the other one is located…. any idea??
