Notification Preview Always Show

I have all of my notifications for each app as “always show preview”. But only for Facebook, whenever I get a notification it says “You have a new notification” instead of what the notification actually is. It says this on my lock screen and banners. Sometimes the notification actually says what it is, which is weird. Also it is the same page that I am getting notifications from so that should not matter. I have looked on facebook settings and it is not an error through their all. I have an iphone 11 plus and just got ios 16 yesterday. I have turned off my phone and turned it back on, i have turned notifications on and off. Nothing helps, I understand where I can change to show the preview. But it should not even say that “i have a notification” when I am on my home screen.
