QUARK "og:title" issue on all pages with Swipe Gallery

Hi
I get a stange og:title content on all pages with Swipe Gallery, and only if I'm using the gallery, on all other pages in joomla the system picks up the right title from the menu items.
<meta property="og:title" content="DO NOT DELETE" />
This is an issue as there is a facebook share link on the gallery and when shared in facebook the page title of the shared content ends up being DO NOT DELETE.

Please help, I tried to search Gavick forum and Google but have no idea where this is coming from.

Hi

Do You have an article or page title appear on that page as well ? Please tell me the url to a page with an example of this problem.

Hi

Please send me an access to joomla panel. I've scanned our demo site along with database and there is no "DO NOT DELETE" sentence anywhere, so I believe it was added to Your site somehow.
