After making the change and restarting Home Assistant, are you seeing new log entries for these nodes or old log entries?
As mentioned by popo128, the old ones will remain in the database until they are purged after 5 days (or whatever time period you may have set). Alternately, you can stop Home Assistant and delete the database (all entity history will be lost) or you can use DB Browser for SQLite to delete specific log entries. I provided an example of how to do that here.
