hcp create nodepool agent '--node-upgrade-type' param is mandatory although in --help it has default value

Trying to run without --node-upgrade-type param fails for "spec.management.upgradeType: Unsupported value: \"\": supported values: \"Replace\", \"InPlace\""


although in --help it is documented to have a default value of 'InPlace'

 [kni@ocp-edge119 ~]$ ~/hypershift_working/hypershift/bin/hcp -v

  happens all the time   

    1.on an hosted cluster setup run :
[kni@ocp-edge119 ~]$ ~/hypershift_working/hypershift/bin/hcp create nodepool agent --cluster-name hosted-0 --name nodepool-of-extra1 --node-count 2 --node-upgrade-type Replace --help
Creates basic functional NodePool resources for Agent platformUsage:
  hcp create nodepool agent [flags]Flags:
  -h, --help   help for agentGlobal Flags:
      --cluster-name string             The name of the HostedCluster nodes in this pool will join. (default "example")
      --name string                     The name of the NodePool.
      --namespace string                The namespace in which to create the NodePool. (default "clusters")
      --node-count int32                The number of nodes to create in the NodePool. (default 2)
      --node-upgrade-type UpgradeType   The NodePool upgrade strategy for how nodes should behave when upgraded. Supported options: Replace, InPlace (default )
      --release-image string            The release image for nodes; if this is empty, defaults to the same release image as the HostedCluster.
      --render                          Render output as YAML to stdout instead of applying.
     

2.try to run with default value of --node-upgrade-type:
[kni@ocp-edge119 ~]$ ~/hypershift_working/hypershift/bin/hcp create nodepool agent --cluster-name hosted-0 --name nodepool-of-extra1 --node-count 2

[kni@ocp-edge119 ~]$ ~/hypershift_working/hypershift/bin/hcp create nodepool agent --cluster-name hosted-0 --name nodepool-of-extra1 --node-count 2

   should pass as if your adding the param :
[kni@ocp-edge119 ~]$ ~/hypershift_working/hypershift/bin/hcp create nodepool agent --cluster-name hosted-0 --name nodepool-of-extra1 --node-count 2 --node-upgrade-type InPlace
NodePool nodepool-of-extra1 created
[kni@ocp-edge119 ~]$ 

A related issue is that we have a difference if the --help is used with other parameters or not :

[kni@ocp-edge119 ~]$ ~/hypershift_working/hypershift/bin/hcp create nodepool agent --cluster-name hosted-0 --name nodepool-of-extra1 --node-count 2 --node-upgrade-type Replace --help > long.help.out
[kni@ocp-edge119 ~]$ ~/hypershift_working/hypershift/bin/hcp create nodepool agent --help > short.help.out
[kni@ocp-edge119 ~]$ diff long.help.out short.help.out
