Font style on homepage has changed

Hello!

I posted a question a few days ago but it isn’t appearing in the forum and I haven’t received a response.

Some of the font on my homepage has changed to strong instead of normal. It’s in the Teaser box, blog carousel and the list of recent posts. It’s fine on every other page and wasn’t like this when I first designed the site.

The page is here: http://www.thecompassmagazine.co.uk

Thanks for your help!
