Original install method (e.g. download page, yum, from source, etc.):
Downloaded these 2 files and ran tar xzf
elasticsearch-7.13.4-darwin-x86_64.tar.gz
kibana-7.13.4-darwin-x86_64.tar.gz
I then ran /bin/elasticsearch and /bin/kibana and enabled the trial license.
There was no other load on the cluster or Kibana.

Describe the bug:

I’m trying to import 3 GeoJson files with 7.13.4. I’ve checked that they are all valid using: https://www.itb.ec.europa.eu/json/geojson/upload
One of them imports successfully, but the other 2 cause messages such as this to be displayed after import:
“Indexed 13 features. Unable to index 5 features” AND 1 feature is missing from the map.
After I select the GeoJson file, but before I import it, all features are displayed on the map.
After I add the layer to the map, it appears that 5 features are missing from the map.
The import response JSON contains this: “reason”: “failed to parse”,
There are 8 records (i.e. 13-5) in the index that is created.

I've also checked the GeoJson file renders correctly here: http://geojson.io/

Also, I thought that it could be related to the Arabic letters, so I used http://geojson.io to remove most of the columns, but I still only got 8 out of 13 features imported by Elastic.

Steps to reproduce:

1. Install a single node cluster on a Mac laptop, do not load in any data
2. Create a new map and load in saudi-arabia-regions.geojson
3. Please note, this file also has a similar issue: saudi-arabia-districts.geojson

Expected behavior:

1. For all features to be imported successfully.
2. For saudi-arabia-regions.geojson, I would except a new index to be createed with 13 and not just 8 documents.
3. For saudi-arabia-regions.geojson, I would expect for the map of Saudi Arabia to be completely covered with regions
4. I would expect the same result from Elastic as from http://geojson.io

Screenshots (if relevant):
Please see attached.

Errors in browser console (if relevant):

I tested my 2 GeoJSON files (already attached previously) with http://mapshaper.org/ and the districts imported successfully, but the regions gave this error message:

Error importing regions.geojson
Unable to import mixed-geometry GeoJSON features
