Notification Summary invisible

I have been experiencing an issue that is happening on iOS 15.0.2 Where part of my notifications summary disappears. It’s the strangest thing, when I swipe away a notification that is directly above the notification summary group, I noticed that a blank space appears in my Notification Center.

The only solution I can find is to go into settings and disable notifications scheduled summary. Then when I pull down from the top and open notification Center, the missing Notification reappears.

Here’s a screenshot where you can see the gap where the notification disappeared. You know this is a bug because if I had swiped away that bottom notification, the one underneath it would have moved up to close the space.

I’ve had this happen twice now and I’m not exactly sure how to replicate it, but the issue is real and has happened to me twice.
