Notification trouble, I think?

Hi all. Since the latest 10.2, something seems to be popping up, and I can't figure out if this is a messages thing, a notification thing, or both. Recently I got the automated text from amazon, my order was shipped. I deleted this message, but now it seems like it's stuck. Not all the time, when I push the sleep/wake button to power the device to unlock, i see a "messages, two days ago, your amazon oder..." I don't understand whyt his is here, when the message is absolutely gone from the phone. Using iPhone six S plus, latest IOS you know the drill. I have seen this behavior even when the notifications have been cleared out. Thanks for any help.

#1 A known bug in 10.2

This bug was mentioned in the main iOS10.2 post elsewhere on this site:

In certain situations, VoiceOver will randomly speak the contents of previous notifications which do not appear onscreen visually. This issue does not occur consistently, and the notifications are no longer spoken once speech is stopped or focus is moved to another element.
