Kibana including versioned documents in visualizations - elasticsearch

Question

I have a document with _id "123456", and when I do a GET in Elasticsearch for that ID in my index I can see that it is _version: 2 which makes sense because I updated it.
However in my Kibana visualizations it seems like it is picking up both versions of the same document when showing the results.
How do I exclude versioned documents from re-appearing in the visualization? For example, this record is showing up twice in my bar graph.
Please and thank you
Example GET response:
{
"_index": "censored",
"_type": "censored",
"_id": "123456",
"_version": 2,
"found": true,
"_source": {
... ommitted
}
}
Also I am sure there is only one actual document with that ID because if I do a _search on the _id field I can see this:
{
"took": 1,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"skipped": 0,
"failed": 0
},
"hits": {
"total": 1,
"max_score": 7.53924,
"hits": [
{
"_index": "censored",
"_type": "censored",
"_id": "123456",
"_score": 7.53924,
"_source": {
... ommitted
}
}
]
}
}
EDIT: Things I've tried below
aggs": {
"latest": {
"terms": {
"field": "_id"
}
}
}
and
"aggs": {
"latest": {
"max": {
"field": "version"
}
}
}

Answer 1

So frankly this is just a workaround, if someone finds a better solution I will mark that as the answer instead. Anyway this is how I've been able to prevent multiple records with the same _id showing up in my visualizations on my dashboard:
I just changed the "Y Axis - Count" on all the visualizations to being "Y Axis - Unique Count on field _id"
Honestly it seems silly that I have to do this because I think different versions should just automatically be exempt from appearing in my saved searches & visualizations. I couldn't find any information about why this was happening. I even tried a _forcemerge to try and delete previous versions of records but it didn't do anything.
Would be nice if someone found a real solution.
