Sexy bookmarks disappear from THIS post, appear on new post with header text

Hi guys,

A bit of a wierd problem here:

I notice on my new posts, the shareholic sexy bookmarks appear only if the post text is repeated in the header, which misaligns the site. Latest post:

However, on the previous post a few days back, the sexy bookmarks and also the repeated text is nowhere to be seen:

Something is definately causing an issue with the sexy bookmarks. Can anyone see this?
