"RSS Just Better" not refreshing feeds

I’m using the “RSS Just Better” plugin to display the rss feed from a site I built for some auctioneers: parkauctionrealty.com
The home page isn’t the regular “blog” page, but I’m displaying the last 4 post titles on the home page using this plugin.

The problem is that whenever a new post is made, the feed on the home page doesn’t update. The feed checks out as valid and the feed page itself shows the latest post.

The only way I’ve been able to get the home page feed to update is if I manually go in and change the link to the feed. So if I’m pulling the rss2 feed, I’ll change it so it pulls the ATOM feed, and it will update the feeds when I republish (and vice versa).

Any ideas on why this is happening, and how to get it to work automatically?

Thanks!!
