Orphaned Trigger Events

Please see attached screenshot. This is the result of devices needing to be removed from Hubitat and rejoined due to becoming non-responsive. They haven't caused any technical issues, but it just would be nice to clean up. I haven't found how to do so, including my attempts at deleting all Trigger Events and recreating them. I don't want to delete and recreate the whole rule.

Recreating the whole rule is the only option to remove them. That said, we've been told that they shouldn't cause an issues either.
