Problem with search function

Hi, I have a site built on the blank slate theme, with the search plugin, ‘Search Everything’ installed and running. If I search for something, say ‘meeting spaces’ there are entries with broken links in the excerpt (but whichare not broken in the post ‘meeting spaces’ itself). I don’t know where this strong.search-excerpt is generated for the search highlights, I think it is there by default though and it seems to be conflicting with the link. It is also perhaps worth noting that the post title of this particular result is also ‘meeting spaces’.

The url so you can check is:

http://kubetest.kube.co.uk/?s=meeting+spaces

thanks in advance
