The content of the placeholder should not affect the way it's inserted into the page. So it's a kind of bug.
But the reason is that you have two <head> placeholders on a page.
You can fix the problem simply putting all your code parts into a single <head> placeholder.

BTW Your meta element is not closed thus it is invalid for the XHTML standard. I would suggest adding a slash before the closing ">". Like this:
Code:
<meta name="verify-v1" content="Jm87+NKJSsaXpvaCp2iZkDF5uAQbDzChLWBjozkIw8Q=" />
