@ben.turner I can’t speak for the original poster, but I am also experiencing this issue.
For me, it seems to happen only when pulling down sites that use the Divi theme. I have not had the issue occur when using a custom theme that uses a custom Walker class.
I created a post here about it before seeing this post. This was not an issue for me prior to installing the latest update.
Any help resolving this issue would be appreciated. Thank you.
