I don’t see how it is happening. I use site-origin on all the sites I manage (30 of them) and this isn’t happening anywhere else, on any other Catch Theme…. and I only use Catch Themes.
Seem I need to avoid using a feature image for the last (top) post made in order for there not to be duplication because it is picking up both the image in the post and the feature image as well.
So the question may be then, why is the page image showing at all when it is set up to show feature image on the home page.
As I trial, if I go back to a previous post (not the topmost) and delete the feature image, then save, there is no image at all showing then on the front end for that post. So it is not picking up the page image once the post drops from being the top one.
So in essence I now have to remember to put in the feature image for the last one made, each time I add a new top post.
It’s very strange.
