Once you are done then use this website to broadcast/update those events across all the major relays. By the way this will also increase your discoverability and data availability across relays.

Let me know if it's solves the problem, otherwise we will explore some other ways.
Last backup is too old, so no good. And I have a relay that can rebroadcast events to all online relays, so I am good on that front. 🐶🐾🫡
Now it's started making sense, that broadcasting relay has broadcasted your incorrect events to all the existing relays. It's same everywhere. Maybe some relay operator can help you. They can solve this very easily.
