A recent change to microceph *1 caused the default crush rule called replicated_rule to be removed. Instead a rule called microceph_auto_osd is created on single node deployments. If/when the cluster is expanded sufficently a new rule called microceph_auto_host is created automatically and existing pools migrated to use this, all this is done automatically be microceph.
This change stop a profile being set at all to take advantage of this new behaviour.
