Home page appearance

This feels like it should be easy, so maybe I’m maybe missing something obvious. I’m helping someone build a website, and initially it was in a blog format with a non-static homepage. Now he wants it to be a regular website format with a static homepage and he wants the homepage to look like the Homepage Default style for this theme. I’ve switched everything over and designated the home page and I have the default style selected in Theme Options, but his home page still has the style of one of the subpages, and I’m not sure how to fix that. Any suggestions? Thanks!!
