History appearing as 'related stories' on Use It All

Writing this as a blog:

Just easily and quickly updated Use It All's front page, in this case by adding a new poster (image) to the events calender story, and selecting Front page/featured. No problems. But the page - now published - shows a set of 'history related pages...' on the righthand bar. I can't work out what is triggering this, as none of my checked 'related sites/pages' etc seem to be directly connected to our multi-faceted ever-growing history project. One for Monday's face to face meeting, me thinks.

Currently finalising the Press Release for our 'soft launch ' of our Historic High Street Stroll major implementation, where every property in the Street is shown, as they were in the past - past being a few years ago to more than a century. We're very excited about this evolution of our community site.
