Dynamic Headers not working for Scheduled Posts

Using Dynamic Headers with Atahualpa 3.7.13. It seems to work fine for posts published immediately, but when I schedule a post and set the header, it looks fine, but when the post is actually published, it reverts back to the default image.

If I can’t get this to work, I need a different plugin. Does anyone know how to fix this?

Or, does anyone know a plugin that works similarly?

Thanks!
