Blog Post Not Ordering By Date of Publication on Home PAge

Site URL: https://www.meatballamericano.com/

Not sure what's going on but there is one blog post on my site that won't move position of first post on the page. If you look at my site it's the "struggle makes the heart grow stronger" one. Despite not being the most recent post, I can't seem to get it to fall into chronological order. For example: "perfect pantry" was published todaty. And yet it still comes in second on the home page. I tried changing/checking the publication date, no luck. When I make a duplicate, it automatically fills the second post position on the home page. Something about this particular post is telling it to be #1 and remain there.

Help is appreciated. Thank you! 

Doh!!! Thanks, Mate!
