    3.The mapi machine created success, and mapi one's paused shows false, capi one's paused changed to true. But according to enhancement doc https://github.com/openshift/enhancements/blob/master/enhancements/machine-api/converting-machine-api-to-cluster-api.md#summary-of-the-rules-outlined-above, this should error and the mapi machine should not be created.
