Blog Post Title Disappeared

I just noticed that the title to a blog post that I published recently is no longer displayed at the top of the page. The author of the post and the author’s avatar is there instead.

Any ideas why this might be?

On the list of posts I also noticed next to this one what looks like a tiny grey thought bubble, which when I click on it, takes me to the status of the post. None of my other posts have that.

My site is: https://concretemoomin.com/
And the post with the missing title is: https://concretemoomin.com/2015/01/27/personal-history-my-old-home/
