Doubled featured content pictures – how fix?

Hello -- We've been a very happy fan of Gridalicious for some time now, and it's always worked well. Recently, something changed on our site and now we're getting doubled featured content pictures. Where we used to have 3 columns, three pics, the heading, and then a content excerpt, now we have picture, heading, picture, content. None of the other site editors says they have changed anything, and I've gone back and double-checked all the theme settings, but I can't find anything to account for this change. I don't hit our home page often, but I believe this was a fairly recent event (maybe last 2 months max). Site: Any suggestions on what to check for, what might cause the picture doubling? BTW, if I remove the featured content image on each of those pages, this problem goes away, but so does the homepage picture. The actual page itself displays fine, and as expected. Thanks! Bruce
