Current Behavior

I'm using this config to scrape RDS ReplicaLag metrics

      - namespace: AWS/RDS
        name: ReplicaLag
        regions:
          - eu-west-1    
        dimensions:
          - name: DBInstanceIdentifier
            value: mysql01
          - name: DBInstanceIdentifier
             value: mysql02
          - name: DBInstanceIdentifier
            value: psql01
          - name: DBInstanceIdentifier
            value: mysql-01-0

but, exporter show me only last DBInstanceIdentifier value

# TYPE aws_rds_replica_lag_average gauge
aws_rds_replica_lag_average{account_id="",dimension_DBInstanceIdentifier="mysql-01-0",name="ReplicaLag",region="eu-west-1"} 0```
