Chunks & indexes not getting deleted from cassandra storage even after setting retention period

Question

Below is my schema config for loki

  schemaConfig:
    configs:
      - from: 2023-09-24
        index:
          period: 24h
          prefix: loki_index_
        chunks:
          prefix: chunk
          period: 24h
        object_store: cassandra
        schema: v11
        store: cassandra

Below is my storage_config

  storageConfig:
    cassandra:
      addresses: cassandra-test.custom.domain.com
      keyspace: new_test
      SSL: true
      CA_path: /etc/ca/combined/privateKey
      tls_cert_path: /etc/tls/combined/tls.crt
      tls_key_path: /etc/tls/combined/tls.key

Below is few table manager config values

tableManager:
  enabled: true
  retention_deletes_enabled: true
  retention_period: 48h

Now chunks and indexes are getting created in cassandra instance but those are not getting deleted after retention period.

Below are chunks & indexes from cassandra storage

 table_name
------------------
       chunk19624
       chunk19625
       chunk19626
 loki_index_19624
 loki_index_19625
 loki_index_19626

Below are my table-manager pod logs

Is there any config i'm missing to add ??
