Hi,
I never heard back from you about this. In any case, I think I found the issue:
In functions.php, I changed line 76 to add_image_size( ‘thumb-image-onecol’, 1800 ); which was cropping the stacked images. Not sure what else that will effect, but that certainly helped for that problem.
For the blog posts, for some reason the post meta option for Title Overlay Min Height is autofilled to 500 and, even though I have Standard media display selected, it’s still applying to my image. I resolved by deleting “500”, but it seems like a bug as I would have to do this for every post.
