cluster-init CLI done changes on the server even if parameter not specified error thrown

[Output of Cluster-init]

/opt/couchbase/bin/couchbase-cli cluster-init --cluster=localhost:8099 -u Administrator1 -p password1 --cluster-init-username=Administrator --cluster-init-password=password --cluster-init-port=8091

ERROR: option cluster-init-ramsize is not specified

There are two problems:

1. Why cluster-init command done the changes on the server if parameter was not right.
2. Why cluster-init command done the changes if server was already initialized. It should fail that "Server is already initialized, to make any changes use cluster-edit command"

NOTE: cluster-edit works fine.

[Output of cluster-edit]
/opt/couchbase/bin/couchbase-cli cluster-edit --cluster=127.0.0.1:8099 -u Administrator1 -p password1 --cluster-init-username=Administrator --cluster-init-password=password --cluster-init-port=8091
