I may have fixed it. I went ahead and removed the first image that was not showing as featured and reuploaded it.
I just remembered, when I first uploaded this image I realized I wanted to change it on photoshop. So i made the change in photoshop and then went back to the listing, deleted the image and uploaded the changed version. But, I didn’t change the title of the image. So, when I removed the image and uploaded the new one with the same name as the old it must have freaked out the site somehow. Then later when i went to it the image was in there twice and what I explained about in the original post happened…
So, I suppose this isn’t anything you need to do something about or not… I imagine it may not happen often if ever again…
