These are by design by kube to be left over. You can set following if you don't like seeing "historical" replicasets.

Clean up Policy You can set .spec.revisionHistoryLimit field in a Deployment to specify how many old ReplicaSets for this Deployment you want to retain. The rest will be garbage-collected in the background. By default, it is 10.
