Changing @timestamp makes data unqueryable on grafana

Hi there. Heres the conf file.

input {
file {
path => [
"/Users/garrett/Desktop/failures-march-legacy.csv",
"/Users/garrett/Desktop/failures-march-cms.csv"
]

   start_position => "beginning"
   type => "changes"
   sincedb_path => "/dev/null"

}
}

filter {

csv {
  columns => [
      "SR #",
      "Customer",
      "Change Owner",
      "Cross Tower Review",
      "Cross Tower Reviewer",
      "Cross Tower Reviewer Status",
      "Senior Manager",
      "Squad Leader Approval - Hypercare",
      "Summary",
      "Data Center",
      "Logical or Physical?",
      "Severity",
      "Scheduled_Start",
      "Scheduled Finish",
      "Environment",
      "Change Type",
      "Service Line",
      "Reason for Failure",
      "Code",
      "Caused SEV1?"
      ]
}

date {
  match => [ "Scheduled_Start", "M/dd/yyyy HH:mm:ss", "M/dd/yyyy HH:mm", "ISO8601"]
  target => "@timestamp"
}

}

output {
elasticsearch {
hosts => ["localhost:9200"]
index => "test"
}
stdout { codec => rubydebug }
}

@timestamp is changed correctly. The data is correctly uploaded to elastic, verified by a get request. But when I try to create a new dashboard, it seems that the data cannot be queried by grafana to create a new visualization.

Could you be a bit more specific? Do you get any error message, for example?
