Fixing the Link Preview Title for Your Podcast Page

I have a custom page built as a homepage for my podcast. The page's title is "ReImagining Liberty Podcast," which is what shows up in the browser tab if you open it. But for a reason I can't figure out at all, when I share the page (on social media or elsewhere), the generated link preview instead shows the title "Aaron Ross Powell," which is the name of my beehiiv newsletter. Is there a way to fix that? https://www.aaronrosspowell.com/c/reimaginingliberty
