Question on what should be obvious. Using SDD for 6 months now, and one thing I can't solve is how to delete historical (old) error codes.

I've run the SDD "delete all codes" tool. Current "unrelated events" codes are deleted. These old ones stay on. There's a long list below the ones pictured.

They mostly seem to have been posted when disconnecting/reconnecting the battery to work on the car. None are relevant to the cars current conditions. The car runs fine, and the old codes seem to be related to no true problem or condition that occurred at the time.

What at am I missing? Just want to delete them. Thanks!

Old Codes won't delete
