The outdated content on Facebook is most likely a cached version of your old theme. To refresh this cache, paste the URL into the debugger on this page and it should wipe the cache and load your new content:
For the Preview notice, that can hang around even after you've published the theme you had previewed. There should be a "Close Preview" button/link on that bar. Click that and you'll no longer be in preview mode.
@Spinturnix I don't understand what to do with the information. I pasted the URL www.ohanaboardshop.com into the Facebook debugger and got this message. I have no idea what this means or how to fix it. Thank you for your assistance.
The fb:app_id message is just a warning, not a critical error. If you scroll past that warning, you can see a link preview. If this preview does not reflect recent changes, you can click the "Scrape Again" button and it should update with the new content.
