What are best practices for no longer needed life events?

We have a life event we no longer want to use. But it has been used/processed in the past. One of our benefits managers end dated the life event. So now we see a blank life event (no name) and date that it happened on people that had the old life event. This also caused an issue with the Benefit extract for some of the people that had the blank process.

So I'm wondering what is best practice for maintaining life events when they are no longer needed? End dating caused a problem and shows blank life events, which look weird/seems incorrect. Do we  update and remove criteria and rename life event to "DO NOT USE" -xxxxx? What are the recommended steps to 'retire' a life event?
