Count not accurate in Visual

Versions (relevant - OpenSearch/Dashboard/Server OS/Browser):
2.12

Describe the issue:

I have inserted 10k records into opensearch and when I run _count, I can see a count of 10000.

GET /conversations/_count

{
  "count": 10000,
  "_shards": {
    "total": 1,
    "successful": 1,
    "skipped": 0,
    "failed": 0
  }
}

However, when I go to Visualize and select Count as the Metric, it is only returning 728. The date range is set for 15 years, wider than the inserted data.

Found the issue… my data generator was adding records in the future (ie > now)
