Recent videos not showing when logged out

Our live site is showing the most recent videos as being 4 weeks ago, but when logged in, I can see more recent videos form today and recent weeks, which do not show when I am logged out.
Live page: https://www.truthtree.com/content-for-you/blog-webinars-more/

Logged in I see these: https://share.getcloudapp.com/8Lugwp0D

Any ideas on what could be happening? I have cleared the cache in YourChannel as well as on the site.server.

Thanks.
