Can't Edit Alt Tags on Posts

Is anyone else experiencing this odd issue where the Alt Tag isn’t editable for a blog post?

We had added some blog posts by copying content from an RSS feed from our old site platform prior to make the domain switch. Unlike the blog posts that we imported via CSV when we click the wrench icon we get a blank box where we’re supposed to edit the alt tag. However, when I looked at the source code in the browser the alt tag information did copy over with the image.
