Why did the calories change for this meal?

This meal is the first meal I ever cooked from Hello Fresh and one of my favorites. I saw it pop up for my menu in a couple weeks and selected it, but I was surprised to see the calories at 1170 — I didn’t remember it being that high, and I try to keep all my meals under 900, with the majority being the “fresh” selections.

I had this meal the first week of January and the calories there were 820. What gives?
