Preview Images Disappear once WP Media Added

This suddenly started happening last week.

As you will see with the “Foggy Bottom” post, it’s missing it’s preview image. I thought it was a theme issue, but I had the InkTheme guys look at it, and they figured out the problem is when I add a WP media object into the post, it gets rid of the preview image everywhere on the site. Ideally, I want the post to be able to put images in it while still having a preview image like it’s supposed to.

HELP!
