Gutenberg Media Library Issue: Just checking, is anyone else who is using Gutenberg also seeing this issue?

In a nutshell, the media library is showing the list of images as though they are not attached to posts, but they are. And the issue is only present for posts posted with Gutenberg.
For example, the top image, of the leaves, is in fact attached to a post. it is attached to the post He, She, Him, His, Her, Her
Why do I care? It’s because I use ‘Unattached’ as a filter to clear unattached images. The unattached ones are usually old header images and that kind of thing.
