HTML head section cannot be deleted

I am running the current release of Discourse. I added a simple div to the “HTML head” section then attempted to delete and save the now empty “HTML head” section. The save says successful, but the HTML is still showing up on the site. I can replace the HTML with normal text and that saves and changes successfully, but it will not allow me to reset that “HTML head” section back to default (blank). Could this be a bug?

Update to latest, fixed this last week.
