Replication Factor 3 but ownership total only 100% rather than 300%

I'm having a strange issue with some Cassandra clusters on a set of Solaris servers. Each of the clusters has 3 servers with its replication factor set to 3.

[admin@unknown] describe resolve;

WARNING: CQL3 tables are intentionally omitted from 'describe' output.
See https://issues.apache.org/jira/browse/CASSANDRA-4377 for details.

Keyspace: resolve:
  Replication Strategy: org.apache.cassandra.locator.SimpleStrategy
  Durable Writes: true
    Options: [replication_factor:3]
  Column Families:

But when we run the "nodetool ring" command it is reporting that each server owns only 33.33% of the data.

In all other clusters with the same settings they report 100% ownership. From this it appears that the replication factor being used is still 1. The other odd thing is that the nodetool ring is not printing out the "Replicas" line when our other clusters do. All our clusters are currently version 1.2.5.

I've tried running the "nodetool repair" command on all the nodes and re-ran the "update keyspace" command to set the replication_factor but the ownership percentage remains unchanged. Is there anything else I can look at or check to see why this is happening?

Edit:

This is what I normally see in my other clusters:
