Could you point me to one of the posts where you experience the issue, so I can take a closer look?
You can also use Facebook Debugger to check what Facebook sees when browsing that post:

If there are any errors there, it should tell you why Facebook fails to select an image when building the post preview.
Let me know how it goes.

For example…
If you share this post, it’ll show the featured image on Facebook.
http://www.junavalove.com/nsv-day-13/
But it won’t share the featured image on this post.

it won’t share the featured image on this post.

That’s interesting. It looks like Facebook picks a different image, although it can see the correct image among your Open Graph Meta Tags:

I’m afraid there isn’t much you and I can do about this. I’d recommend that you contact Facebook about this, and ask them why a different image is used in post previews, in place of the image used in the Open Graph Meta Tags:
