Hello Zee-
Thanks for reaching out. This is the first report we’ve had of this issue, but I was able to replicate it when I tried it out. I’ve filed a bug report so we can get this fixed as soon as possible.
When I tried it, the only image I could see was the same one I’m trying to replace. Does that match the behavior you’re seeing?
If that matches the problem you’re having, I did find a work-around. When the BoldGrid Inspirations plugin was also installed and active, I could get the rest of the images to load by switching back-and-forth between the Library and Upload tabs. If you don’t already have it, you can download BoldGrid Inspirations directly from this link.
