Hi Edward - thanks for responding. The keyspace could not have been created more simply:
create keyspace KEYSPACE_NAME; According to the help, this should have created a replication factor of 1: Keyspace Attributes (all are optional): - placement_strategy: Class used to determine how replicas are distributed among nodes. Defaults to NetworkTopologyStrategy with one datacenter defined with a replication factor of 1 ("[datacenter1:1]").

Please include the information on how your keyspace was created. This may indicate you set the replication factor to 3, when you only have 1 node, or some similar condition.
