Extra html in page

<p>Hello,</p><p>I am using Boldgrid to build my posts.   I have built my whole site, but their remains an issue which I can’t solve.  I believe I need to cut the templates somewhere to do it.  If you go to the page.  http://www.moviesbyespresso.com/2020/08/16/art-film/   or you can get there from by going to the front of the site, the first large image on the left at the top, and clicking on “Art House Films  a cult following”  You will see the appropriate image from the front page, and below that the verbiage: “Art House Films:  a cult following;”  And below that: a blue box;  and below that is the text that is suppose to be there.  The  problem is the blue box.  </p><p>What template file do I need to cut to fix that and do you have the correct coding to replace it with?</p><p>Greg</p><p> </p><p> </p><p> </p>
