Can’t clear old notification

…and it’s driving me slowly insane. Every 12 minutes I get a notification that I missed two telemarketing calls on May 2nd. I have missed/not taken several many calls since then but as of approximately three days ago, my Versa 4 insists on notifying me of these two.

Things I’ve tried:
- Hard reboot by holding the side button
- Shutting down the watch from the menu
- Refreshing the app
- Combinations of all of the above while the watch was on the charger

Any other things to try before I give up and switch to an Apple Watch? I need the notifications so I can see during the day when I need to pull out my phone and address a call/text.
