Index.lifecycle.rollover_alias does not point to index

[forthgate]

I use ELK 7.3 and i got next template :

 { 
"order":3,
"index_patterns":[ 
  "logstash-airflow*"
],
"settings":{ 
    "index":{ 
       "lifecycle":{ 
        "name":"airflow-policy",
        "rollover_alias":"airflow-rollover"
     },
     "refresh_interval":"10s",
     "number_of_shards":"3",
     "number_of_replicas":"1"
  }
},
"mappings":{ 

},
   "aliases":{ 
      "airflow":{ 

  }
 }  
}

And index created with pattern
index => "logstash-airflow-%{+YYYY.MM.dd}-1"

{

  "airflow" : {
