My “Perfect Games” Number Changed from 5 to 4 on Steam. How can I fix it?

hey everyone! last night i realized that one of the games from my perfect games number doesn’t show on my achievement showcase anymore. i know this is a minor issue to everyone else but i care about it lol. is there any way that i can fix it? is this a bug? i thought it would resolve itself after a few hours but it’s still there.

for some context: i completed the game PockeDate a week ago and deleted the game off of my PC last night and that’s when the number changed, so i think it has something to do with that.

first image is the achievement showcase and the second image is when you press on “4 perfect games”

anything feedback is helpful, thanks!!
