Datastream and indices not rolled over or deleted

Hi,

I recently started using datastreams, however, I see that the datastream and indices are not getting deleted according to the lifecycle policy. I can't seem to figure out why they are not getting deleted. Any help or advice will be appreciated.

Template

{
  "index_templates" : [
    {
      "name" : "logstash-template",
      "index_template" : {
        "index_patterns" : [
          "logstash-*"
        ],
        "template" : {
          "settings" : {
            "index" : {
              "lifecycle" : {
                "name" : "logstash-lifecycle-policy",
                "rollover_alias" : "logstash"
              },
              "number_of_shards" : "3",
              "number_of_replicas" : "0"
            }
          }
        },
        "composed_of" : [ ],
        "priority" : 1,
        "data_stream" : {
          "hidden" : false
        }
      }
    }
  ]
}

What's the current status of the policy?

Are you referring to ILM status?

{
  "operation_mode" : "RUNNING"
}

I should have said explain, not status, ie Explain lifecycle API | Elasticsearch Guide [7.15] | Elastic

Here is the explain output from one of the older indices that should have been deleted by now.
